I have made this RGB LED tie. One of my friends and me had the idea at 2 am and now it has come to reality :D
It runs on an Arduino nano, 8 rgb leds and is powered by a 9V battery.
I have prom tomorrow ('abschlussball' in german) I probably won't wear it during the official part but definitely at the party after prom.
The current animation is a bit too fast (I was listening to hardstyle while coding it) for the music they will play tomorrow at the party so I still have to make a slower one.
Tell me what you think about it :P29
I'm not moving at 50km/h. Not even close. I'm sitting in my chair.
Just because I plugged a wire in backwards doesn't mean you are right.5
Just did some initial programming of my Arduino to run the alcohol sensor.. seems to be working well. So, looks like it's time for testing 🤤 cheers!32
Since I already got all the stuff working for the devrant client on Arduino, why not port it in other platforms ?
So here it is DevRant 3DS client18
I once designed my own Arduino IDE compatible microcontroller, and even had the card manufactured.
Sadly I've yet to actually use it for anything, but hey, achievement unlocked, right?15
Just made a laser sentry tower for my cats. Next up is adding some tracking so it can play with them by itself while I'm at work and after that I'm adding a Wi-Fi module and camera so that i can also play with them while I'm at work... I couldn't resist using a mouse to top it off 😂17
That personal Arduino project I made for my own use, is now going to the Paralympics in Rio with a potential medal winner.5
HOLY FUCK I DID IT
I wrote an Arduino code for my friend. I didn't have any board at the moment to test it, but he flashed it the next day, and EVERYTHING FUCKING WORKED!!! AT THE FIRST TIME!!!11
1024 points of soldering !!
Wasn't expecting that when I began, but it's quite interesting and the result will look amazing ^^
I'm making a LED matrix from 0, controlled by an Arduino, it will look really good when it's finished, I plan to use it to display notifications, clock, sound spectrum etc...
What do you think of it ? 😇15
Got some new toys today! A Raspberry Pi 3 and a Arduino starter pack. Any suggestions on what I should do with it?23
Got annoyed by the super bright default theme of the Arduino IDE. Decided to make a dark theme for it! Turned out pretty well!
Unfortunately there is no official way of themeing right now, therefore I had to edit some files in the program's directory, which was a pain in the ass to do... (and kinda scary)
I tried to adapt the Material Theme in Sublime Text btw.
Here's a comparison:20
Want to finish my little friend for a long time now. He can dance Michael Jackson's moonwalk for now.
Idea was to use the sonar sensor to switch dancing styles but he is still blind :(11
#define redLed 2
#define yellowLed 3
#define greenLed 4
void setup ()
pinMode(yellowLed, OUTPUT) ;
pinMode(greenLed, OUTPUT) ;
void setup ()
for (int i=2;i<5;i++)
pinMode (i, OUTPUT);
Proff - This code is wrong it won't work. Where have you specified red led, green led, yellow led?
Me - wtf! Code doesn't know which led is used in what pin it's just pin numbers!
Gave me less marks 😑
P. S. I wrote comments in my code specifying which pin will have what led connected 😑14
It's time for another teacher story. So grab a cup of tea and listen.
We were casually talking about Arduino programming because he told me he teaches this in another class.
Teacher: it's so sad that i can't use my java code on the Arduino. I mean the Arduino uses java so there shouldn't be a problem.
Me: *internal* HOLD THE FUCK ON
Me: you know that the Arduino uses c and not java, do you?
Teacher: but the Arduino can do java commands! How do you explain this!?
Me: because java uses the c-syntax and it's more of a coincidence that they're named the same way?
Teacher: huh. Ok. But C# doesn't use it, am i right?
How can someone this dumb be a programming teacher 🤦6
My first rant, so pls don't blame me?. 🙈. No just kidding, but now the Story. A friend told me that he want to start hacking. But I know that he can't prog or use a PC. But I asked: "Can u program?" He: Yeah, of course!?". *Me wondering as fuck* Me: Where do u learned that?" He: "Watched YouTube Videos!" Me: "OK?, and what language du u want to use, and IDE?" He answered: "Language Arduino, and IDE what is that?". *Me facepalming and asking myself what dafuq was he watching and why is he trying to do things like that*11
Alrighty then, so you can do this and it'll still work...
Like, I suppose technically speaking it makes sense....20
A client asked me if I had some software to make an .exe file run on Android.
So I replied with:
Yes, you need to run the RNN through a HM05 then cross-compile the output with a MOSFET.
My arduino mega just arrived. My home will become a slightly smarthome (All diy) so excited.
Best part it will not touch privacy12
Arduino, all the way...
I have a burn out for 3 years and a few months ago I found arduino.
Burned lots of money in components in the first months because I got so addicted.
No regrets, helped me a lot, been learning a lot and keeps me focused.5
I was checking an Arduino sketch I wrote in a hurry 2 years ago. I want to cry for the number of shit I've found there 😓
Picture + I had put as int variables that should have been boolean. I needed them for 0 and 1. As well as with no comments and no explicative names.13
I was working on an Arduino counter (an inside joke) and I somehow sent 12V to an IC I was using.
it burned out.
I'll leave now3
Spent all day on this.
Debugging hardware is fucked man...
Wanted to make a devrant logo like always (its my Hello world to test my CNCs now).
And.... When I finally had the machine calibrated... The pen stopped working lol.
I'll just continue tomorrow, it's finished...
Probably gonna use a few times and make a bigger one.27
Sitting in the hall, quietly listening to an Arduino tutorial and I bring up terminal cuz I didn’t have the IDE and unnamed teacher starts yelling at me for hacking?!? Fuck ignorant teachers.15
Just finished my CNC.
Lots of problems but it works... More or less.
Need better steppers and other drivers. But I did it, learned a lot, did lots of mistakes, and don't get me started on debugging hardware...
Z axis unfortunaly can't even pull the motor up lol.13
I have reached the point where my main project with my arduino collection is building a sex robot and i dont even feel the least bit ashamed about it.10
This is my desk right now, anyone else who really enjoys fiddling with arduino / rpi electronics stuff?
Like making a remote for the projectors in school or using an Ethernet switch and a raspberry pi to create a WiFi network :P34
For my final project as a first year computer engineer, I have to implement a FAT32 file system using a bare metal c++ compiler that will need to work on arduino uno/due....
I've only been in the computer engineering space for 2 months.
Not sure I can do it, but I'm going to try my best!
Wish me luck10
I've got an Arduino now and I was building lights the last weeks to understand the coding. But when it comes to use full stuff I could do my mind is empty. Do you have any suggestions for me?
I know there have to be FUCKs in a good rant. So I will miss use the tags...14
Just thought I'd share my current project: Taking an old ISA sound card I got off eBay and wiring it up to an Arduino to control its OPL3 synth from a MIDI keyboard. I have it mostly working now.
No intention to play audio samples, so I've not bothered with any of the DMA stuff - just MIDI (MPU-401 UART) and OPL3.
It has involved learning the pinout of the ISA bus connectors, figuring out which ones are actually used for this card, ignoring the standards a little (hello, amplifier chip that is wired up to the +12V line but which still happily works at +5V...)
Most of the wires going to it are for each bit of the 16-bit address and 8-bit data. Using a couple of shift registers for the address, and a universal shift register for the data. Wrote some fairly primitive ISA bus read/write code, but it was really slow. Eventually found out about SPI and re-wrote the code to use that and it became very fast. Had trouble with some timings, fixed those.
The card is an ISA Plug and Play card, meaning before I could use it I had to tell it what resources to use. Linux driver code and some reverse-engineering of the official Windows/DOS drivers got me past this stage.
Wired up IRQ 5 to an Arduino interrupt to deal with incoming MIDI data, with a routine that buffers it. Ran into trouble with the interrupt happening during I/O and needing to do some I/O inside the handler and had to set a flag to decide whether to disable/re-enable interrupts during I/O.
It looks like total chaos, but the various wires going across the breadboard are mainly to make it easier to deal with the 16-bit address and 8-bit data lines. The LEDs were initially used to check what addresses/data were being sent, but now only one of them is connected and indicates when the interrupt handler is executing.
There's still a lot to do after that though - MIDI and OPL3 are two completely different things so I had to write some code to manage the different "channels" of the OPL3 chip. I have it playing multiple notes at the same time but need to make it able to control the various settings over MIDI. Eventually I might add some physical controls to it and get a PCB made.
The fun part is, I only vaguely know what I'm doing with the electronics side of this. I didn't know what a "shift register" was before this project, nor anything about the workings of the ISA bus. I knew a bit about MIDI (both the protocol and generally how the MPU-401 UART works) along with the operation of a sound card from a driver/software perspective, but everything else is pretty new to me.
As a useful little extra, I made some "fake" components that I can build the software against on a PC, to run some tests before uploading it to the Arduino (mostly just prints out the addresses it is going to try and write to).46
My fiance is also a programmer. He doesn't say he loves me often, but than he does it looks/sounds like ''I [less than 3] you'' 🙃
Or he will prefers to ask me what am I cooking for dinner by using arduino & a display 🙄2
I've spent three days trying to upload some code to my ESP8266 and it failed every time. Now I just plugged the Arduino at my Desktop and it works. Notebook USB port does not provide enough current I think.18
Today's project, turning my diy convencional milling machine into automátic.
Status: it works.
Features: motors are to slow.
Solution: need better motors.10
Has anyone here ever used tinkercad.com? (for simulating Arduino setups, or other circuits)
Where can I find community content for circuits? They make it so easy for their 3D models.. But not for their circuits..
Also, can someone tutor me in the basics of circuits over telegram?
(for those of you whom have never heard of it, I attached an image ^~^)14
Went to see my brother today. Before I could say hi, I saw the following:
- Desktop, Windows playing video
- Thinkpad, Linux mint, Arduino IDE
- Arduino board with some sensors
- Complaining about light theme
I've only thought him a bit of C# and SQL. They grow up so fast :')
(Before today, I only knew he was gonna learn Python)3
Yesterday I accidentally fried my Arduino Mega with the heat of a thousand suns, but I got a new one!11
I just spent 2 days debugging why this shitty arduino project doesnt work. Then i noticed disconnected cable.
Fuck my life.1
Four hours of work.
You think you write spaghetti code? I write spaghetti wires.
H-Bridge dual motor tester for stepper motors.
Speed is controled by pot.
H-bride are L293D.
My third board, and the first that won't go to the trash.
Question. With the baterry off the motor continues spinning with the 5v from arduino.
My question is, is the L293D suposed to do that? Or do I have a short circuit somewhere that is giving power to the motor? Meaning it can burn the arduino.
Runs a 12v stepper from a CD-Rom driver perfectly at 5v from the arduino and actually starts to act strange when I turn the 12v on. (maby the circuit it's adding 12v + 5v?)25
It all started 9 years ago when my dad buyed me an arduino then it goes on and will go on for my entire life.
And yeah i was studying on my own no help at all no curses just try and error.
My first Drone
Arduino nano + L293D + hc-06
Objective: learn how to use Bluetooth with Arduino.
V 0.1 (no direction, commands by serial terminal).18
My resolution for this year:
- learn PHP
- be a pro with SQL and learn PostgreSQL
- build couple cool hardware projects with Raspberry Pi and Arduino based on C.5
I am working on this project for school where I am building a simple 8-bit keyboard thing.
It works for about a day. Perfect.
I was about to put it all away and leave for the day. Then it starts playing random notes and doing random things on it's own.. I was like WTF!??!!
I just unplugged it and put is away (I was too lazy to fix it)
Now I am back at it again and have taken the entire thing apart and rebuild it 2 times.
Then I find the problem...
I forgot to ground a button.
So now I am just sitting here staring at a wall and have completely given up on it.
Btw.. you can check out my mess of undocumented code on GitHub
i really love coding because in C# you write string, and in Arduino String( with a capital s). You mess this up and nothing works.
10/10 would rewrite the whole program again because of this.11
Good morning, good day and good weekend.
Sometimes babysitting is worth it Hehehehe.
No projects today, resting day, me, the pool, my nephews and a arduino basic manual.4
God knows how many morons try to brag to me on how they know hardware programming because they own an Arduino, whenever I say I study Electrical Engineering.5
It took me a week but I managed to build an Arduino that opens our office door when we use a command in Discord or Slack. Probably the best project I worked on during my internship.2
3 hours making this beautiful circuit to test stepper motors.
Arduino nano + L293D + pot
Fucking bitch has a short circuit somewhere and can't find it out...
Made the same project in a breadboard in 15 minutes and it's working.
Fuck hardware bugs.
Cutted in the middle of all connections, took out excess solder... Nothing.
Fuck it, moving to the next ideia20
When you order a bezillion tiny things at small prices to avoid toll on one large package, and you have no fucking clue if everything has arrived.
Arduino stuffs, LEDs, resistors, stuffs like that wherever its cheap for those wondering.5
Here is my collection of microcomputers and stuff... I have quite a few and don't know what to do with them...
Arduino pro mini
2x Arduino pro micro
Raspberry pi B+
USB to serial interface
Some random Arduino interface
What should I do with them?8
That moment when you’re asked to shift the entire project from arduino to raspberry pi because your professor likes jazzed up crap.
Arduino so freaking reliable. A gem in a box.
Raspberry Pi is flashy hollow shiz.9
Hey folks, this is ben.
Just a little story of me and IOT
,for the past few months, i have been working on various projects on Internet of Things and, with the little exposure... I have seen so much goodies that come along, i love the robust and realtime architecture that IOT has, on my platform i use
Arduino, esp8266 and Android, i am able to control my car park, home lights, and my pulse rate using the few components.
At first it was hustle, but now? Am loving it😋😋😋,
If you wish to join me or have a project of the sort..... Just holla me up :email@example.com
I can also teach for free.13
Just won a Raspberry Pi + touch screen in an Arduino robot competition. What can I do with this little beauty?10
->buying fake arduino from ebay.
->have to install separate drivers, because the manufacturer uses a cheap usb to serial chip.
-> driver page is all in chineese, only the download button is in english
-> installed the driver(at this point there was no going back)
-> instand kereal panic
Why the fuck does Arduino use C++ macros for min, max, abs, etc. ???????
For those who don't know what a macro is, basic example:
#define abs(x) (x > 0 ? x : -(x))
Which looks like a function, but instead abs() will be replaced by the expression and all x will be replaced literally with what you pass to abs
would evaluate to
(i++ > 0 ? i++ : -(i++))
which would call i++ twice
I guess I will have to double check every built in function and rewrite it if it's a macro -_-. Not taking any chances. Btw all Arduino functions are in one big file, so now I have to pollute my code with namespaces.
Macros can be great but what the fuck.15
I finally did it. Finally had the energy to do... One axis for my CNC lol.
It works perfectly.
But the 28BYJ-48 are so slowwww.
- One Arduino Uno
- Two 28BYJ-48 with Uln2003A controllers (Y is already programmed)
- One joystick.
Arduino + Bluetooth + L293D + car Chacis and 4 DC motors.
Finaly finished my second bot/Drone.
Actually finished it yesterday but had lots of problems with hardware bugs (learned so fucking much in a day).
Tought I fucked two unos with bad soldering... No they are fine, just won't turn on in the circuit that was already working (was fine running the code).
Redone everything from scratch with a arduino uno, it's perfect now.
Funniest part is how I got my hands on a 50€ car kit for almost free... So some Chinese store sended this kit instead of some cheap stuff. Saved another arduino with the chip rack (that one that you can trade the atmega chip), I'll save it to program single chips. Plus a h bridge and lot lot more cool stuff.
Used only the Chacis.
Next: esp8266 and camera... And maby a gun? Would be cool34
So I made this simple lamp that shows what is current build status on Jenkins CI.
- Change color depending on Jenkins build status
- Automaticaly turn on/off if user is logged on Hipchat
- Beam effect if somebody makes coffee
- Unicorn effect if food is delivered
- Big red arcade button that can send random message to somebody on Hipchat
Arduino has a FLASH memory that stores data even without power. FUCK why did nobody tell me that sooner. 6$ to hell on that fucking SD module and 12$ on fucking SD. Well gotta rewrite that code.16
Just found my ultimate project for Arduino...
Have to make this untill x-mas and take it to the company x-mas dinner11
Arduino just Rick Roll'd me. Their buzzer example code plays the tune...so I hooked it up to a photosensor and threw it in a cabinet...next time my wife opens the cabinet, the light flooding in will trigger the song. I have a comfy couch 😂4
New Kickstarter project reward in the mail :)
The tau (yata), smaller than I expected! Excited to find a tiny project for this!7
This thing is too good. I think it's the best hack I've ever seen !
Regarding my last rant: I AM FUCKING DUMB!
When I receive data from the master Arduino, a hardware interrupt runs and oversteps my main loop stuff!
Lesson? NEVER WRITE HARDWARE LATCHES ON THE MAIN LOOP WITH A HARDWARE INTERRUPT WHICH IS MOST OF YOUR FUCKING CODE!!13
So I'm using a temperature sensor to detect the air temperature in a box. I'm getting readings of about 225°C. Thinking that's weird I check the algorithm converting the input to celceius. Seems legit. Okay must be hardware, let's try resetting the sensor into the board. Turns out the readings weren't lying... Long story short, if you reverse the polarity of a temperature sensor you get a very powerful heater...5
Well, I got 2 mega arduino kits and a raspberry pi over xmas (and no experience with either), plus unemployment, so my goals are learning the hardware side of things this year.
Also, hi devRant.3
Target for airsoft.
The prototype bullseye didn't survive the trials but it works. Just need to upgrade to wood.2
DEBUGGING ARDUINO IS A FUCKING PAIN WHYYYYY
FUCK THIS PROJECT
FUCK PROPRIETARY DEBUG HEADERS
Arduino & ESP-32 without the arduino library.
Good look finding any example code. It's just you and datasheets with fontsize 2.5
Doing Arduino in school, well normally i code in java/php.
But its better than the stuff, we usually do here😊4
3 weeks of search, but now, I have a miniUPS with solar and dc input for my raspberry pi Zero with cam.
I have developed a little ble4 iOS app to monitor all voltages and relay states.
All this shit from China, about 50$ except rpi and cam.
What you think?9
I didn't see a post for it but a decent book bundle for Raspberry Pi and Arduino is on Humble Bundle at the moment.
HUMBLE BOOK BUNDLE:
DIY ELECTRONICS BY WILEY
Get Learning Python with Raspberry Pi, Electronics For Dummies, and more!
Thanks guys for the help in the last weeks.
This is what I was so hard trying to print.
Btw... reminder to self, plastic expands. That's why the stepper has duck tape instead of screws lol33
When you find another student code..... it repeats the same code for the LCD in 340 lines of if ;-)2
Just spend 35 € in two arduino uno, a generic kit and sensor kit. Now must wait a month...
Already thinking on shit to do...11
everything mounted, was going to connect Z and motor...
And the fucking X stepper isn't working...
The plastic piece that made the steps is overused and can't handle the weight :(24
Haha its fun reflashing memory on router via arduino as serial connector.
(Just installed OpenWRT)
Well im Linux guy. Sooo it was builded by somebody else sooo fuck that lets build my own image with YSB support and looooot more. This router will be a beast.
Fuck. The entire day to do this shit.
The screen was my first experiment, but because of a bad module (i2c) it didn't worked.
Today I finnaly got it to work.
Starting making everything almost like in the picture, everything mounted (and lots of black hot glue, no wires showing...
One hour breaking everything apart without damaging the screen... Was a loose wire.
Started again... Didn't work...
The pot is also damaged, sometimes it works, others need to turn it hard.
New set of wires.
Soldering everything right, testing all wires so no mistakes this time... But it takes so longgggg... Making everything in modules this time (to reuse without having to sordering again. And finally... It works.
By this time I should have 3 or 4 learning projects finish (I really wanted the screen to adapt all output in text, no serial, no blinking less, everything in modules, code prepared so, when I get my 40+ packages from China I already have a prototype tester ready.
10 hours... Fuck I'm really addicted, or else I would just solder everything together :D28
Evaluating some WiFi ESP8266 modules. 01, 12S, 14. Programming is very simple with Arduino IDE and esp8266 community.
This iot world really excite me.
ESP-01 about 1$, oled display about 2.5$...
Project is to create my own HomeKit modules. (Relay switch, temps, garage door, etc..)10
I'd never imagine that my interests would shift from webapps and servers to embedded devices and measuring 500volts with an arduino....1
I fucking HATE the Arduino environment right now.
First of all: you can't fucking put your project files in a sub folder to the main file. I can't write #include "src/motor.hpp" because it doesn't fucking know what that means.
Turns out you have to put all your header files in the fucking library folder common for all Arduino projects!
Secondly, you can't call your cpp headers hpp, they HAVE to be called h, or the Arduino environment throws a fit and begins whining about being unable to find the fucking files.
Not just that! You can't reference other Arduino libraries from within your library because the environment doesn't know what that means either.
To get around that you need to fucking include the library in your main file, AND THEN you can include it in the library file that uses it. After all, it should be the programmer's job to soon feed a so called IDE, right?
I'M SO FUCKING DONE WITH THIS SHIT! 😤
I'm ready to either program the Arduino directly with an AVR programmer or even port the entire project to the raspberry pi where I have a proper fucking Linux environment with a proper fucking directory structure so I can code proper fucking C++.
Hell I'm even fucking willing to spend all weekend porting all the code myself if necessary.
It's not reasonable that correct fucking C++ code is invalidated because I called the files something "wrong" and put them in the "wrong" directory.
"user friendly project board" my ass12
Since I mostly see frameworks to use with G-Code in Arduino CNCs I'm gonna make my own framework, where you don't need to know G-Code and the code is executed by Arduino code.
The code would include a template to define steppers steps and such.
Would include a library to work with different stepper shields.
Would this interest to anyone?
I'll provide a full example with stuff to learn for any amateur working with CNCs or that want to work with one. If you're not interested, thank you for reading, you can stop here.
This framework would only use incremental coordinates and will work for basic forms, drilling and such.
Coordinates can be relative/incremental or absolute.
Lets say you have a square with 10mm, (top coordinates: (X=0,Y=0) to (X=10,Y=10).
think your drawing this square.
Third Line (...)
Absolute is a fixed point (coordinate)
Relative is a distance to move (not a coordinate but the distance and direction)
So, to cut a square with a TR10 (end mill with radius=5, diameter=10)
// You don't place + in positive values
// The tool always cut in the direction of the tool rotation, meaning on the left of the material.
Z(10); // Security Distance
XY(-5,0); //Compensate the diameter of the tool in radius
Z(-1); // Z=0 is the top of the block to mill, in this case. Z=0 can also be in the bottom
Y(15); //Second Point
X(15); // Third Point
Y(-15); // Forth point
X-15; // Fifth Point
Now we have a block with 1mm depth. If you use a while or for you can repeat the sequence for x=n passages, change the value to Z for the depth and your done.34
Smoking a Joint
Infected Mushroom on Youtube
Arduino in my front, just recovered a damaged module, drawers filled with new gadgets to try (new to Arduino, is so addicting I don't even play anymore)...
This is life
The only thing lacking is a blowjob...21
I don’t know why, but I can literally call another Arduino and tell it to load sata from a fucking SD card but can’t show the word “MEM” on my SPI-controlled screen... what the fuck5
I spent a whole day, finding out why I getting wrong, random data from keyboard, which I modding at the moment. I tought - there is nothing can be easier than interfacing AT keyboard with avr. but... after many hours of googling I got it. My fucking DINOSAUR have XT(IBM PC) keyboard protocol (I even didn't know that it was existing)1
aaah, memories. When I discovered github while doing my school project. Even my lecturer had no idea about, he thought I made it as part of my project 😂 Project was an Ionic app connected to Arduino for home automation. straight As I got... straight As.
Soon I will be talking about a new communication protocol between Raspberry Pi and Arduino ... At the meeting ... IoT enthusiasts.
I am excited and slightly upset.7
I have a 16 year old son who is off-and-on showing interest in learning electronics. He wants to work for NASA someday. I’ve looked at dozens of Arduino and Raspberry Pi kits but I feel like he would benefit not so much from “mostly done for him” types of kits that are more like toys, but the kind that teach more fundamentals like resistors, capacitors, transistors, relays, etc. In other words, knowing first what the principles are behind the fancier kits. Do any of you have a recommendation of kits that start with the fundamentals, but that can still be inspiring and engaging?13
Why the fuck does python think that 50 <= 10 ????? This is so annoying!!!
Anyways.. I am working on a devrant client for the Arduino for matrix display..5
That moment you ordered a "starter set" for arduino just for the cables, servo and sensors, buy an arduino uno because it wasn't listed in the set description and now you have two...
Never thought it would be so cheap (25€ for the set apparently including a arduino uno)9
Code works yesterday with the hardware but but doesn't work today (ﾉꐦಠヮಠ)ﾉ, they only work when they want
Helped somebody learning Arduino (he is new to programming in general)...
I saw this at the top of his file...
I admire his effort tho...14
Can't do anything else (level it and such) until I get new motors...
the steppers I ordered one month ago returned back to China, FUCKKKKKK
one more month waiting.
So many project ideas.... nothing concrete.
What should I do now? Did my BT controlled car, the CNC, ... Any ideas?9
My first C++ app for a client was leaking so much memory that Windows kept crashing too.
So I had to press Ctrl-Alt-Del every few runs.
But the laptop running the app was enclosed in a box, so the keyboard was inaccessible.
My hack was to set up an Arduino, a push button outside the box and a wire. Asked the steward to push the button every three people trying the system. So the Arduino sends Ctrl-Alt-Del and the app was running again.
The client was happy :)
Every time I'm organizing a beginner level programing workshop with a especific language, someone asks if we'll get to use Arduino with it.2
Fucking exam on Electronic Building Blocks... (aka Arduino). Program this thing ON GODFORGOTTEN PAPER! And then these retards put in that assignment line: max 5 lines of code, for a function that does nothing more than divide two shit eating numbers! And half of my apparently vegetative class fails this! When you were allowed to use your book and notes!
Oh and also, here's a seemingly pissed over image of an arduino with some peripherals, draw the wires. Draw! How the fuck do I keep 21 cocksuffocating wires on a page without overlaps or unclarity?
What would be the most awesome thing you've done with technology yourself ?
I mean, having Arduino to run your smart house is pretty cool, but is there a way you can top that ?8
Well I've been down last months due to a burn out and medication.
Last ween I finally got my first arduino, then second and two kits...
Now I'm addicted...
Stopped Proscriating with games.
Started learning electronics and shit, specially , started cleaning... And just did my first project :p13
That feeling when you spend 2 hours debugging circuit + code, to find out that the arduino had gone loose in the breadboard...1
@Condor did you mention this?
One of my final projects... To connect gas, movement, IR pir and do a all arround protection sistem. I'll build the on-off for the gas difectly in the box for the arduino, it's the easy way, since I can now make an app to control it online.
Sorry forgot the pic20
My bed IS WAYYYYYY better than yours....Music reactive lights on bed...gotta make friends now to party :(
I think I just burned 2 Nanos.
I'm using a 30W soldering Iron and had to resolder the pins of one and solder the pins of a new one.
Now they don't work. One allows for code upload but won't turn on, other seams to have a short circuit.
Could have I burned the circuits due to a 30W soldering iron?
Also used a little of flux on the pins, can flux pass energy and make bridges?
I just finished running my first Arduino program, I am perfectly able to switch the led on and off.
Should I add it to the CV!!!
Or should I build the whole traffic light three leds first?!?
I am confused....2
Did anybody ever to use this arduino module (RC522) ? How to test that module is working or not? I've tried many example in the internet, but still not working4
First day of vacation, on a remote village cause of covid, after months of doing nothing special I made this :D
It's a keyboard to do combinations of keys (prototype) ...
Well, I made it to play sound effects in games (on voice chat)....
Ya, having a burn out fucks your motivation. At least I did something2
#arduino #led matrix
So, this is my first led matrix using a 74hc595n, I did all the connections right, isolated the cathodes (-), and when I tested, I only connected one cathode (to test one row, when almost all the lights turned on, in all rows doing a chacing... So I disconnected the negative wire and it still works.
One led in the arduino blinks (L).
GND is only connected to the shift register
All the rows light up doing a colum chase when there is no negative.
So the new Arduino Portenta h7 is programmable in JS. Some people just want to watch the world burn!5
A few years ago I had a Minecraft server and wanted to create my own plugins for it. I failed, but never stopped trying.
Did an internship at a software development company and got an Arduino as a gift; I was hooked - controlling stuff and seeing that stuff happens because of my code? Count me in!
Took classes in school that teach me coding and databases. I also taught myself a bit of C#, Java, C++ and PHP.
5 years and 3 internships later, I'm finally starting my paid training for the job as a programmer next year at the company that gave me the Arduino.
Gaming is what got me into coding, and I couldn't be happier. :)
New work place (changed the PC bellow (so now I have just a little more room.
And the stuff that arrived in 10 days.
Only arround 90 packages to arrive, all arduino or eletrónics related...
Must up my credit card limit
... Reached maximum this month.
No I only need that energy I had before the brake down.. Maby forcing me to finish the projects I already have in mind.
After all, I need a cnc to make my projects, so I must make one3
Batteries and power.
Hey guys. I have a question I have to rectify so I can think without doubts.
Let's say I have a sistem with solar power, a 1 lipo battery, one lipo module and arduino + shields and I want to power only by the 🔋.
My question is: is it good practice to charge while discharging at the same time with a lipo module? Won't it damage the batery and incrise the chance of fire? Thank you6
Sort of follow up to: https://devrant.com/rants/1351833/...
Now I can turn on/off my PC over the Internet. A little hacky but it works like a charm.
I'm using an Arduino IDE compatible ESP-12E with on board WiFi and a homemade optocoupler (LED + photoresistor).
Hopefully more projects like these are coming 🤗4
I wanted to build a smart home system with arduino or pi when I'd have my own place. But since that is a ways off, let's park that.
Just learn me some linux, python, node, typescript and some js frameworks, maybe handlebars, knockout and angular?
I’ve been trying to implement an alarm clock as an example for my physical computing lecture but the merge of my existing low power clock with my existing state machine based timer is driving me nuts. And I’m the lecturer of this course!2
Seeing code control things in the real world is the most satisfying thing ever, I'm getting a robot car kit Soon and I'm so excited2
So the gf just came home, threw this in my face (literally, but not intentionally) and said "they were giving these away, thought you might have fun".
I've only heard of raspberry pi, arduino and such, but never actually used one.
Anyone have any experience with this thing in particular? Can I actually do anything with it or is it mostly for learning?8

The feeling when your brothers think you are a magician cuz you play music by pressing lemons with arduino.
Then they tried and it didn't work ubless I was holding them.
When life gives you lemons, don't do a lemonade. Do an arduino program and play!1
The Arduino programming language (.ino) is so easy to understand and learn
But trying to make the equivalent in raspberry pi whether it's in c or python is just not as elegant as Arduino :(((8
Arduino project going off the budget and teacher asking for more functionality because "it can be made within 30 mins". We are working for 3 days and only things we are getting to know is new components that we need to add. That too in summer holidays... Fml2
So I have to give a technical presentation in front of 50+ people in 6 days. I'm just about shitting my pants right now. And thinking what to talk about.
Any ideas? Mine are:
1. Arduino and Raspberry Pi--the future of automation.
2. Privacy and how personal information is now another way of profit.7
Been receiving packages every day but today I good good shit..
Ideias for me to try?
4 relay module, 4 mostef board, finally the gears for the motors I'm scraping, and more mostefs. My mom is saying that I have the mailman for myself lol2
Anyone got any cool arduino/pi projects they want to share? I'm currently iteratively building a self-hydrating cactus that measures the soil moisture content and sunlight and logs it to my server, just because i can, then waters the cactus for me if it needs it.4
Hey guys, my gf and I want to do something with the Arduino we got. We are getting a CS degree, so programming is not a problem, but we have quite basic knowledge of electronics.
What could be a cool simple (but not too introductory) project we could do?
The arduino came with a bunch of sensors (ultrasonic distance sensor, humidity, ...) some input (joystick, RFID reader/writer, buttons) and some outputs (LCD display, 8x8 LED matrix, bunch of color and RGB leds).16
Coding for MCUs gets more and more surreal every day.. On one hand we're cooding oldschool heavy metal C or C++, but on the other hand they tell you to use PuTTY to check if there is a working serial connection - what the fuck?
Also the IDEs they suggest you. VSCode or Eclipse. Both are so unbelievable unusable for this, even with plugins, I would compile this shit via CLI myself before using them.
It just feels so contrary - they act like professionals and just spit out 200 uncommented lines of C to start WiFi on the ESP32 - not explaining a single fucking thing, but on the other hand, they checked the connection via PuTTY after writing some uwu kawaii shit into Eclipse.
Not to mention Arduino with their FUCKING SKETCHES.6
Firebird V(arduino based bot) while charging made some sound and one of our teachers who teaches microprocessor came in and switched off the charging and when asked about she said she thought it was some kind of bomb.😑2
They said they make their coffee with ****** Arduino !! So I went back to check out the machine. Not what I expected....2
I took me the whole day of wondering and debugging to see that I was checking if a variable was 0, to set up some stuff, and the variable was only incremented after that check, but I had a return statement inside of it. So it just went in, saw that it was 0 and returned, over and over. And I was wondering why the fuck nothing happened... because that method got executed every second or so and should've moved the motor.
Gotta love your hardware programming. Either you do it right the very first time, or you spend the whole day staring at a piece of code, compiling, throwing in console prints etc.
Its 1 am, where I live btw.1
OH MAN it feels so fucking good achieving something with electronics, especially because I have a really hard time learning it by myself
Throughout the years I slowly bought more Arduino boards and stuff. But then RadioShack closed shops in my country. So my inventory has remained relatively small.
But now I have been given a ton of stuff. Boards, sensors, wires. More than what I know what to do with.
Someone, please give me a cool project to make.8
Just set up my own IoT device for free thanks to the guys at Losant.
I met them at codestock a couple years ago. They were running a workshop with some Adafruit boards and at the time I had never seen anything like Arduinos before. I was fascinated. So I walked up and asked about it. They said they sold the chips just to demo their IoT stuff. I said I'd buy one. I then waited like 40 minutes for them to get their card reader working. They gave up and handed it to me, gratis. That started my dive into electronics from programming.
Few years later, I needed a remote temperature sensor to make sure a certain unattended appliance never got below freezing. I suddenly remembered that kit (now buried under my heaping stash of electronics), followed the tutorials, and had the exact thing I needed up and running in like a few hours, with all the bells and whistles I could want. And for free.
The icing on the cake here? I went on their website to look at a kit to replace it. I found one with even more goodies in it, and the entire kit cost less than the cost to go to adafruit and buy just the board alone.
Thanks Losant for being awesome. If you wanna do IoT anything, look em up.
It's finally working.
Just needed to upgrade the drivers.
Using RGBL + 3 28BYJ steppers.
Just have one tiny problem and need help...
The resolution isn't right... Instead of moving mms, if I send a move of 64mm (one stepper revolution) it just turns one time instead of moving 64mm... Where are the settings to change this?
Btw this is the best birthday present ever, from me to me :-D also... My parents bought me a 3D printer, waiting for it to arrive... Me happy today34
I'm part of a robotics team in my highschool. We work on autonomous robots, which are driven with microcontrollers like the Arduino and "bare" Atmel chips.
Last year we were using a protocol called CAN. CAN is a bus which runs at 1Mbps and it is quite easy to connect devices together. (It's a bus ofc it is). BUT... it needs a terminator at the end, mostly 120 ohm.
Every year we are on a deadline and something broke on our current board and we needed to solder up a new one, but we couldn't find the 120 ohm terminator... ANYWHERE!
At end after searching for it in the workshop for 4h straight (12am- 4am) we finally found it, and soldered up the new board and guess what... it wasn't what we thought, the code was the problem.
After realizing the problem my teammate and I, in silence just stood up, packed our things and went home. Argh!2
I want to start with Arduino stuff.
Some tips which board i should buy?
Or some tips for a Hello World or something like this?11
Although some of you might say that arduino is a good introduction to programming, I believe you should teach a kid basic python or java before getting into arduino or raspi..etc11
Ucglib, a universal TrueColor library for many display controllers for Arduino. Seriously, this thing’s documentation is fucking SICK. They include so many fonts on there, every single one is customizable and every customization is documented.
Probably the Objective-C syntax documentation, it’s DIABOLICAL, you have to, first of all, FIND IT. After that, you need to understand the shitty language.1
Goin on vacation tomorrow night... As expected to have two more days.
Started packing everything for my new addiction...
I usually take two cases, with everything I want, even a laptop. So space is already filled except my stuff and clothes.
Already have 3 cases... only with electronics stuff :D1
Had Arduino for months, couldn't get MPU6050 working, because of a lack of time and other stuff. (Need it for long term college project, data logging blah blah)
Gave it to project teammate to figure it out, who hates even touching hardware, BTW.
He figures it out in an hour (adjusting baud rate for supply voltage)
I feel like a complete idiot.
Can you spot the difference?
So after getting the 37 sensor arduino module kit, i decided to label each of them. The 2 modules below are the last 2 in need of labeling...
One is a magnetic hall and the other is an analogue hall but I can't tell which is which. Googling just makes it worse since they are so similar the same image is often used for both modules. The only visible difference is one has a small resistor and what appears to be a tiny led.
Please help me identify them... asking for a friend.15
Why can't I still figure this shit out?
This is supposed to be easy!
Its a freaking USB communication!
It IS easy.
So why am I stuck?
I got shit ton of stuff to figure out and this is where I'm stuck?
A while ago I ranted about how the programming club in my school decided to start teaching programming with arduino and it was causing the students to drop out because they were finding it hard, well today I went to the club and got there 10 minutes late, yet when I arrived, thinking that they would have started without me, there was only 2 people other than the instructor and assisstant. And the funny thing is that although 90% of the class stopped going to the programming club because they were finding arduino hard, the instructor still doesn't want to teach anything else and is adamant on teaching them arduino.
What a fucktard3
My arduino based self flying plane..
Busy with it for more than a year now and progress is pretty slow because I want to develop a UI to control multiple planes and drones..2
You guys prefer Arduino or Raspberry PI? I want something thst is beginner friendly but super intuitive. Leaning towards arduino5
So we were building this thing with a raspberry pi, a few sensors and a few motors but for some reason we could not interface a sensor with the pi (this is supposed to be trivial) so we interfaced it with an Arduino and had connected a pin on the Arduino to the Raspberry pi to alert the pi when the sensor reads something!
Not something we were proud of but we had time constraints and couldn't figure out how to make it work. Also, the thing we were building was just for a one time use so we thought it would be okay
Well, I have only one:
When programming an Arduino, unplug the power cable. I nearly burned my Arduino Uno once...1
Does anyone know good resources to learn Arduino Programming?
I have a basic understanding of C, I am looking for a series (of articles preferably) that walks you through the available libraries and the electrical engineering side of things.5
Ever visited https://www.instructables.com ??
DMNNNN I just can't leave... So many cool Ideas...
I don't have anything to do with the site, found it yesterday while searching for arduino stuff, and MANNNN .... It has the best pratical tutorials I ever saw... Not like most, where they teach you the basics...
Most sites, first arduino APP, light a Led
Instructables, First App, Instructions with pictures and videos on how do connect the Arduino, install IDE (this is the most basic tutorial after all). then the tutorial, Light 4 leds and do a lightshow...
I'm In Love
Btw, new project, got my old Niko Dc Car working again, after like 30 years...2
I've been using instructables a lot for arduino tutorials. Do you guys know other sites like that?14
I accidentally slept on my hand and blood accumulated inside it and now it looks like a balloon.
I guess I can’t work on the Arduino project today.
Devrant lost it content, cuz there is nothing more to complain about. Everyone has already told their story. So normies come to fill the void. People who know nothing about technology except getting likes. Mostly with lame to mediocore posts that are rather far fetched in order to be called dev related.
Also a lot of good ppl seem to vanish over time. AlexDeLarge, Alice, Jase, Linuxxxx (thou he's back for now) and dfox/trogus.
Looks like we are soon going to hit a devrant depression.6
K guys... Don't expect to hear much from me for a few days...
Not like jase. It's just....
I upgraded my CNC last night with "real" steppers (only need one more for Z)
I just got my 3D printer and have a puzzle to mount...
First pieces I'll do (after tests and learning curve) are pieces for my third CNC lol2
Bought an Arduino and is finally able to learn how to make my software interact with custom hardware projects. Just wiring up a led and controlling it with software is amazing fun! Really looking forward to learning servos, motors etc.
Planning to make velocity sensitive midi drums with piezos in the future.4
Do you guys think I should go for a Lego Mindstorms set as a way to start getting into robotics?
I know of a lot of people that recommend going through arduino and buying a bunch of shit and throwing it together etc. But the thing that makes me interested in Mindstorms is how everything seems to be in one place. A smart brick programmable through multiple different programming languages(for example Python, java, C) a good kit that can be really modular and built into different components, all sorts of sensors.
I just think its a good option, but if someone were to recommend a particular book or resource for Arduino or some other stuff I would definitely consider it.
So, what do you lads think?14
Trying to get my SPI SD card reader to work with hwlib...
I can't get the fucking library to do what I want...
(I have to use it, it's a requirement for the project)
There goes my fucking weekend...
About getting Help.
I've been needing lots of Help and explanations about small electronics and Arduino stuff.
What is the best to place such questions, where we do really get answers and replies to noobs?
Or anyone here, one of the Arduino / Electronic Pros who doesn't mind handling my questions :p
Favorite affordable (<$200) beginner robotics kits?
Played around with Arduino a bit in the past, and Mindstorm, and a little vex.7
Had my first programming encounter when I was 12 at school with Turbo Pascal and VB, I was the best in my class but didn't really got struck by it.
It wasn't until I was 19 that I discovered Arduino and Processing, started learning C++ and Java and decided to switch from Electronic Engineering to Computer Engineering.
Since I was into music and used to make guitar pedals, the first things I programmed were a bunch of audio effects with Pure Data and some controllers with Arduino since I wanted to make a digital pedal with a raspberry, but as usual I never completed it ¯\_(ツ)_/¯
Can't find help for this.
I want to program my arduino with my phone, but ArduinoDroid doesn't detect the Arduino while the device detects a USB device plugged in.
Can't find any help so don't know if it's my android (xioami mi A1 Android 8.1, soon Android 9). Anyone who uses that knows?5
How about for once in your fucking life, before saying that my code is wrong because it is giving you errors, you fucking check to see if you have the semicolons in place
Lost one day mounting my CNC.
Still on the basics...
Found out that I baddly welded the two fucking easy drivers and made a bad connection I can't undo now.
So the drivers are always on and stepping :(
5€ to the trash.4
I'm trying to do something different from the usual and need your help.
I want to install linuxCNC in a pen drive (as in a live CD, but with the file system in the PEN which is usable)
I want to plug it into my mother's laptop, use it with my machines, then just unplug and it will run the native windows for my father.
How can I do this'?
I only find Live CDs, and I'm afraid of ruining my OS when If I try to install (afraid of installing on the SSD instead of the PEN).10
Wanted to switch from Arduino IDE to VSCode. Arduino extention is now open source and debugging is now possible! But not for the boards we use... Of fucking course it isn't and they don't even mention that properly. Screw you and your half arsed features!3
what do you guys use to control your DIY CNCs?
I'm using UGS, Universal Gcode Platform, but it has a slight problem... doesn't work with functions.
Meaning, I just had to write a 75 lines program that could be an 8 line program If I could use loops and GOTO...
Also, what CAM software do you use?13
Think I'm gonna branch out from dev for a minute and try my hand mucking about with my arduino kit! Any cool ideas guys? Robot Arm seems to be my prevailing will so far4
Why the fuck does a freaking SD card reader for arduino needs a 3v and a 5v pin...... I have no space in my project and no experience at all to handle this.... and no fucking place for batteries....
Why is every of my project like this ..... cry12
What can I do with my spare Android devices/boards? Could I use the board with a custom OS for a Pi/Arduino analog?
I have 2 tablets that I have no use for. Googling suggestions are pretty simple and nothing that repurposes the hardware.7
The fucking nail to my coffin. This thing is so unreliable. I fixed on issue get the next one. Then get an error trying to make a http request, with little information on the web. Eventually switch to FTP which is working for a while. Then suddenly nothing is working properly. Even the serial communication has errors. This process took over 6 months. Constant debugging and headscraching involved. After hundreds of hours I give up. I'm going to switch to a Raspberry Pi Zero with an UMTS Stick attached. This is going to cost way more battery time but my project needs to be finished by july and I'm tired of this shitty little module.2
So I bought a LattePanda off Kickstarter last year and only just put it in its new home. Struggling to think what to do with it. At the moment I only use it for streaming video. It's got an Arduino chip in it. What would you guys use it for?9
Just bought an arduino starter pack, so excited to begin, but I can't start until after I've went to the gym and had dinner, soooo muuuuch tiiime. :D
Oh and I'm going to receive a cisco switch kater in the week to.program and hopefully a router to, next week is going to be awsome!
How do you fuck around on a breadboard/arduino if you have sweaty hands? And don't say stop abusing Amphetamines.3
I have a friend that asked me to make an app to interface with Arduino when he realized that I develop Android apps.
The annoying thing apart from him nagging me to make it, is that he still doesn't know what he wants and how it will work...5
question for the hardware guys.
How can I run a brushless motor without a ESC ? like a CD-Rom brushless motor.
Can I do it with an arduino + h-bridge or maybe an ULN2003A??
All of our products have a 16x2 lcd. Every April fool's we make all of them say some offensive/funny stuff. One year I made an Arduino controller for one of the other engineers units it took him a few hours trying to figure out how I was doing it 'cause he couldn't fix it.
Arduino Nano, Problem uploading
I ordered a few Nanos from China, but I can't upload the code since they are clones...
Did anyone get around this? Would appreciate the help.15
i feel its a great time to be a developer we have so many toys to play with
machine learning, scientific python, nodejs, frontend js frameworks, nosql, NLP, elasticsearch, mongodb, open source .net, big data with java, arduino..., VR, 3d printing
what toys are you playing with?
Anyone else got the problem of a tmp36 being really fucking hot. Its really annoying.
I was just messing around with a Arduino and there is this Love-o-meter thing that uses the tmp36. And oh god something must have went wrong113
Differences between Arduino Nanos.
I have 3 Nanos, 2 MCU, and 1 AU and I can't find information about the differences...
Arduino store only sells one nano, but I know that MCU and AU are different packages.
Besides the different architecture and look, I can't find information or something that I could see the difference...
For visual view: https://aliexpress.com/item/...3
I want to do one project in which using arduino uno and RFID reader to take attendance but for this I have to need 100 reader card which is costly. So I thought using bar code so I can print barcode on paper and no need any card. So does anyone idea where I can get bar code module for arduino uno.4
For the fucks sake, friend sent me code with ton of shit like that:
Is there some nice short guideline how to wire nice clean Arduino/C-based languages?5
was making quine McCluskey calculator on Arduino, does 100% of work, didn't slept properly for 3 days, didn't bath for 5 days, investment ~90$.
group didn't paid their part of money.
The teacher just said keep the project on table and leave, I didn't even got to demonstrate it. FML.1
Show me how you made an http server with an arduino nano and an esp8266 via AT commands from the arduino, the arduino handling the clients.
No you didn't, this shit is fucking impossible.6
I spent about an hour today working on getting an arduino board working before discovering that my IDE wasn't the latest version. In fact, it was outdated by several years.
Why are the apt caches so old? I keep my machine updated constantly but what's the point if it's locked at an old package forcing me to circumvent apt in the first place?1
So, I am getting bored with my personal projects right now. I'm thinking about dragging out my Arduino and Raspberry Pi's and tinker with them for a while.
I need some inspiration, though. Just wondering what my fellow tinkerers are (have been) working on.6
I had ".NET Developer" position. In reality, I was doing php, Android, unity, c on arduino, some desktop .NET and web too. Oh, I had to work with nodejs too. I was getting paid 6 times less than now...
So, I really need a laptop, because in is much more mobile, wastes less energy etc
But I'm quite low on budget since nobody will buy my 3 y.o pc for more than 600€. What laptop under like 650€ shall I get which will be good for Arduino and Unity coding?
SIDE PROJECT POLL
Holidays are coming and I have a little time to spend on side projects that I left behind. The problem is that I have not enough time for all of them and I really can't choose one.
So here is a list of them, one for each comment, the one that gets more ++ is the one I'll be focusing on after the 26th.
Please feel free to ask anything and give suggestion if you think it may help :)
Note, in square brackets there is the current state of the project (planning -> pre-alpha -> alpha -> beta) and its age5
I'm an Android dev but now I'm looking to also create cool stuff on Arduino anyone know any good tutorials1
TL:DR I wanna scare the shit out of intruders, do you recommend Arduino or Raspberry Pi?
So, I live in a place kinda like a college, but everyone get their own room. There's staff 24/7, and obviously, I really dislike some of them. Otheres I just like to joke with.
Sometimes, I've thought of putting together a "system" which will probably make them shit a brick.
The way I would do this, is have an Arduino or Raspberry Pi connected to a sensor, which will trigger an airhorn somehow. Yes, and airhorn. They should shit bricks, remember?
That's the beginning tho. Later, if this ever becomes something, I plan on adding some system so it wont trigger when I open the door, along with flashing red lights when intruders opens the door.
I attached a picture. The smaller rectangle is my closet. First circle is the sensor, which I assume can just tell when the door moves, if I place it correctly.
The rectangle is the Arduino or Raspberry Pi, which should control it all as you probably already know.
The second circle is the airhorn. Not sure how I'm gonna trigger that yet.
So, does any of you have some advice or recommendations on how I can make this dream become true? Or even additional components to make it more efficient?
Last and most importantly, would Arduino or Raspberry Pi be best for this, is there a specific model thats better fit?10
Not a setup. it’s for a research project 😂
Displaying from the tv: a bunch of environmental data
At the bottom right: A raspberry pi and arduino both hooked up with (dht22 and bmp085) and (soil moisture sensor and a 16x2 lcd) respectively2
Arduino + breadboard power supply MB102.
Noob question I know, but how do I connect the power supply to the arduino? 5v to 5v and GND to GND? Or vin? Or the other first pin above res?
I was trying to test the ability of the Arduino Leonardo pro micro to emulate a keyboard. Loaded a example and modified it. But I made a dumb mistake and now the Arduino types as soon as you plug it in the same string over and over. So it can't be reprogrammed because the keyboard input of the Arduino is overwriting the mouse input (which is needed to select the port)...
Does somebody know how to fix this?4
Wish me luck. Starting today on building a modular CCTV camera and alarm system for my home.
Gonna try to integrate accelerometers on the windows to detect when the glass vibrates too much or for too long, as opposed to sonic glassbreak sensors, which also trigger upon my son crying.
!Rant - birthday gift 🎂
3 days ago was my birthday and my girlfriend still has to buy me a gift, but she doesn't know what to buy. Now the problem is that I don't know either.
I'd like to start programming something related to IoT and maybe learn a bit more of C/C++ (I guess they could be useful to know), so I'm asking you, what should I (she) buy? Arduino or Raspberry PI 3? Is there a kit of sensors I can buy? I accept any suggestion!
Thank you 🙂13
The moment when your client gives you a Pi Zero and 4 IR transceivers, tells you it worked on Arduino now writes them a driver that bit-bangs them into 4 TTYs.4
I learnt C a while ago and didn’t use it for A semester. One day I needed to write some C code for a small Arduino project and I spent 20 min remembering how to declare an array.3
Knew nothing about Arduino
Attended a workshop
They had a hackathon after it
Won the hackathon
Got the Arduino uno board as a prize
Gotta buy sensors and other stuff though.
*Me so happy*
What should I make now? (Apart from an Iron Giant replica controlled wirelessly thorugh commands)3
Have any devs found any interesting projects with a cars OBDII port. I've seen some arduino shields and libraries for it. Curious if anyone has any cool ideas.1
So last year we started off with an IOT smart home project combined with SAP HANA, everything went well with the hardware side of it. Wired up everything and functioning smooth as butter. When we try to connect to the HANA cloud db to store sensor data... we find out that Arduino isn't supported. A big FML!!2
Last successful dev project ?
Wait there can be such a project ?
But TBH my last arduino project with LoRa was kind of success.3
Anyone know whether Elegoo is any good? The reviews seem ok. Trying to get into Arduino with the kids. https://www.elegoo.com/1
I found every book of Arduino a total waste of money. There are lots of courses free and a lot of documents, projects in Instructables or Hackaday to start to learn. I say it as a teacher and course/document writer.
I'm currently do some freelancing, and the job that I am doing at the moment requires interfacing with a Bluetooth device, but the company wants a Bluetooth repeater, to help extend or amplify the signal.
Is there anything like that out there or a possible Arduino or RPI implementation that I could use?
I know it will be disturbing for a few of you, but it has to be said...
I'm not sure how I need to say this, but...
GOD DAMN FUCK YOU ARDUINO YOU STUPID LITTLE FUCKER WHY DOES MY CODE NOT WORK AFTER HOURS OF REASONABLE DEBUGGING FUCKING FUCK YOU IT DOESNT MAKE ANY SENSE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!2
Thanks for your feedback. I was able to run Opencv on my computer and integrated with Arduino. I will greatly appreciate another feedback. My question is does anyone know the code for the functionality for the brightness and contrast filter?1
I just bought an arduino out of curiosity to actually learn IOT.
I am a business student with 0 knowledge on electronics. What am I suppose to learn first before playing with this device, i don't care about learning curve (i have the time and resources assuming i don't get fired from my current job)3
I'm moving. While doing so I found my old bread boards and arduinos. Maybe I should use them again. Program like our ancient cave dwelling ancestors, get in touch with my primitive side.1
Which Java GUI shall I learn in 2021? I see people are demonizing swing and telling its obsolete, so it would be really helpfull if someone gives an nice Java stack example for developing windows application focused on PLC and other external controller like arduino, raspberry etc, control and visualisation., in general, automation and industrial monitoring and controls.3
Which YouTube channel is good for beginning to learn arduino?
P.S: I'm a web dev without iot knowledge6
Does anyone know a foolproof way of radio controlling a dozen arduinos? I'm working on a big project that needs about a dozen arduinos working with each other.16
that moment when you got just one night to prepare app for arduino based robot with pattern recognition. No hardware component with me and whole thing goes on asumption
Kinda want to start learning hardware (Arduino, RasberryPi etc), any tips?
How it works programming languages and stuff, anyone who can lead me on into it2
Bleh, I fucking hate Arduino. I thought this Chad would teach me assembly for PCs, not Arduino. The boards don't fucking work half the time, I don't give a shit about blinking lights or motors, I don't want to do things with robotics, I just want to fucking code. Ffs, I'd rather write code that just makes a number increment and then quits, because then I wouldn't have to use that useless fucking Arduino "IDE".
Fuck you Arduino, fuck you so much.4
New to the the electronics stuff and I'm building a word clock. Recommendations for a microcontroller that has at least 22 outputs (22 words to light up). Something from Arduino? Also need to plug in for power and use an RTC.6
Trying to run a web page from arduino with some js in it to draw a graph. And it craps out with some error about start tag.
It works fine saved as an html file on my laptop.
We were learning how to code circles to light up in sequence. As it's similar to how code works for Arduino. Cool. Go back to c# in Unity and teach what the code does not just copy.
I am getting this Launch4j error(application unable to start ) in my energia software....can anyone help?1
Anyone knows any high power IoT LoRa boards? I have tried the adafruit and heltech ones, but didn't do much. I need it for a low permittivity environment.8
Which is the best Raspberry Pi board for a beginner to start learning Raspberry Pi?
Is there any Raspberry Pi or Arduino board that I can program in Java?15
I was doing some stuff in to an arduino for a pre-college course project then I got stuck per 10 minutes because of a fucking ; (Maybe because I don't looked at the error box) wtf why this language use so much ; ?? I think I'm going to crazy...
My area of focus is getting paid doing shitty PHP, JS, CSS tweaking freelance gigs and save enough money so I can finally focus on learning electronics and make stuff with arduino, stm32 etc. Hardware interfacing is so interesting.
Hello to everyone!
I was wondering, how to find mate for collaborative programming projects ?
I would like to keep me trained with new challenges during the summer, and I know there’s a section here on DevRant for collaborative project but I find this a bit confusing.
