One of my personal projects.
Just trying something new ☺

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 :P

No, Arduino.

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.

Stress testing my new cnc, say Hello World roundy

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!

I've build remote-controlled, riding flamethrower based on deodorant and ESP8266 (Arduino):

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 client

...arduino

We were in a group project with about 7 people.

One of the guys who ran windows needed to work with arduino and couldn't get it to work after hours of trying.

I suggested Ubuntu and they immediately started to bash me for being 'that linux nazi'.

"shut your cock sucking mouths. I'm not a fucking linux nazi, at least give it a fucking shot."

Well, it worked from the first second.

Fuck those cock suckers

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?

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 😂

Biggest accomplishment so far this school year (it's been 2 days)

My first arduino project... i'm in love with these toys 😍

this made my day!
:D

Yay my christmas present has arrived 😁

That personal Arduino project I made for my own use, is now going to the Paralympics in Rio with a potential medal winner.

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!!!

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 ? 😇

Adding back light for my arduino drawer...

Hobby time...

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:

Got some new toys today! A Raspberry Pi 3 and a Arduino starter pack. Any suggestions on what I should do with it?

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 :(

Finally its done and can avoid obstacles! :)

Other students:
#define redLed 2
#define yellowLed 3
#define greenLed 4
void setup ()
{
pinMode(redLed, OUTPUT);
pinMode(yellowLed, OUTPUT) ;
pinMode(greenLed, OUTPUT) ;
}
Me:
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 😑

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 🤦

Finally!
Quick info panel with Arduino Uno + RPi
:D

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*

Android app controlled robot built in 2 days. App was developed from scratch. coolest project.

Forgot to put a restor in my circuit and pumped 3 volts into a tiny LED :((

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.

My arduino mega just arrived. My home will become a slightly smarthome (All diy) so excited.
Best part it will not touch privacy

Alrighty then, so you can do this and it'll still work...

Like, I suppose technically speaking it makes sense....

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.
You might run into an arduino javascript, but you can bypass that with an stackunderflow or XSS

Raspberry Pi? Nah bro, Arduino is where it's at.

Good morning everyone^^
I just heard my company is doinig some weird shit.
1. We RECOMMEND doing backups on a USB stick (our customers get a cheap giveaway when they purchase our products).
2. We sell farm controllers with less power than a fucking arduino as "Top Notch technology". (single core 1Mhz, 128MB RAM)

We Devs are not supposed to understand this logic. We shall only "make it faster". If proper solutions are suggested it gets shrugged off as "expensive".

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.

Last year in my circuits class we were given an Arduino and tons of sensors and shit, was told to just 'make something'. So I figured I'd make an potentiometer-controlled RGB LED because the potentiometer is analog and the LED is digital. But I didn't have access to a computer at the time so I wrote all the code on PAPER. When I got to school I copied it into the IDE and.....

Worked flawlessly. Proudest moment of my life.

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 now

1 wrong connection in you ECG IoT project and your app declares you dead ! 😂

Spent all day on this.
Debugging hardware is fucked man...
Me proud.
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.

Fucking GARBAGE

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.

!rant
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.

Debugging SPI using LEDs...

This is just the worst

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.

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 :P

Finnaly....
Look who's back.
CNC Machine V3.0

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 luck

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...

Arduino is just cool !

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).

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 🙄

Hello World!

Hello devRant!

My name is Carter Schaap, a maker from SW Ohio. I've been voiding warranties for most of my life, and am currently at Great Oaks Tech School learning HTML, CSS and soon-to-learn JavaScript.

I dabble in C++ (because Arduino is a thing) and I'm learning Python because I'm getting into Raspberry Pi.

I can't wait to get involved in this community and do a lot of ranting.

Have a great holiday season!

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 ^~^)

Try hardware too. Arduino is a fantastic world.

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
- Coffee
- 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)

Today's project, turning my diy convencional milling machine into automátic.
Status: it works.
Features: motors are to slow.
Solution: need better motors.

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.

I clicked ctrl+n button so much and this just happened
Arduino IDE

Arduino project
RC car with Bluetooth controller

I just spent 2 days debugging why this shitty arduino project doesnt work. Then i noticed disconnected cable.
Fuck my life.

Fuck this!

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.

Fuck.

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

Ewpratten/ArduinoKeyboard

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.

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?)

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).

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.

My resolution for this year:

- learn PHP
- advance at JavaScript and figure out what's so cool about react.js
- be a pro with SQL and learn PostgreSQL
- build couple cool hardware projects with Raspberry Pi and Arduino based on C.

But can it run Crysis?

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.

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.

Got some toys to play with

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 ideia

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.

Just won a Raspberry Pi + touch screen in an Arduino robot competition. What can I do with this little beauty?

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.

Here is my collection of microcomputers and stuff... I have quite a few and don't know what to do with them...

List:

Arduino uno
Arduino pro mini
2x Arduino pro micro
Raspberry pi B+
USB to serial interface
Some random Arduino interface

What should I do with them?

Excited to work with my first ever Arduino! 🎉

Wish me luck! Project Presentation today

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.

Save me from this madness!!!

Arduino is like Javascript for Microcontrollers

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.

I took wk119 to clean my desk and make my wife happy (for a short period of time).

WFH Setup has been rearranged shortly and is not finished. Most of the soldering/Arduino/Pi/drone stuff has been removed and will get a seperate workbench soon.

Lightning is not finished as i plan to reinstall the smart lightstripes again.

But hey , cleaning the desk is enough for this week :-)

New project and new stuff! Seems like a good opening for new year!
Happy New Year guys! 🍻

Hey guys.
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 cool

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 :bensalcie@gmail.com

I can also teach for free.

->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)
-> rebooted

A standard device library for Arduino

No need of arduino/pi, 100% autonomous.

Weekend project completed today !! (PS : using cloned Arduino only for testing purposes)

I wrote an application to demo at a convention coming up. Which feeds tcp data from arduino devices to real time d3 maps via websockets.

Demoing today, and the owner starts talking about a project he saw that which lit up some lights to a device in the room via the internet. In this same meeting he casually mentions he wish he had developers who could do that type of stuff.

The disconnect is massive and soul breaking.

New Kickstarter project reward in the mail :)
The tau (yata), smaller than I expected! Excited to find a tiny project for this!

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.

I didnt know what to do for christmass decorations.

So i created 8x8 LED matrix and spent my entire day coding this thing to display any fucking character i give it. Also connected it to Raspberry Pi so that i dont have to reprogram it to say something different. I just use my app and it sends signal to Rpi and then to arduino.

Yes im just bored and i had to create something.

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 😂

Doing Arduino in school, well normally i code in java/php.
But its better than the stuff, we usually do here😊

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?

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.

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...

FUCKKKKKK
FUCKKKKKK
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 :(

Just spend 35 € in two arduino uno, a generic kit and sensor kit. Now must wait a month...
Already thinking on shit to do...

Today's project...
Target for airsoft.
The prototype bullseye didn't survive the trials but it works. Just need to upgrade to wood.

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 lol

FUCK ARDUINO IDE!!!
Had a project with it (~ 1k lines).
Made some small changes to it and presented it.
The fucking thing just hung at a specific animation and I couldn't tell why!!

Turned out the compiler on my laptop fucked up pretty hard with one specific condition:
for(int i = 0; i < repeat; i++) { ... }

Turned out the fuckwit of compiler just kept compiling the "i < repeat"-statement to be always 1/true and thus turning this for-loop into an endless-loop.
Tried it before to debug and got the same result!!!
Compiling the same code on another pc worked fine.
The compiler just can't compile properly. Be aware of it when you encounter a problem on Arduino but can't figure out the cause.

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...
Didn't work.
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 pot.
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 :D

I'd never imagine that my interests would shift from webapps and servers to embedded devices and measuring 500volts with an arduino....

Arduino CNC
Hey guys.
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.

Ex:
X(10);
Y(-5.5);
XY(6,7.5);
Z(-10);
This framework would only use incremental coordinates and will work for basic forms, drilling and such.

<Tutorial>
Coordinates.
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.
First line:
X0, Y0
Absolute: x10,y0
Relative: X+10
Second line:
A: x10,y10
R: Y+10
Third Line (...)
Absolute is a fixed point (coordinate)
Relative is a distance to move (not a coordinate but the distance and direction)
</Tutorial>

So, to cut a square with a TR10 (end mill with radius=5, diameter=10)

<code>
// 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
(repeat)
</code>
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.

It's Rainy...

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.

So I bought a smart watch to go with my Samsung Galaxy back when I was 12, and upon inspecting the watchface maker app I came across lua scripting files. This amazed me. Animations, complex math, hexadecimal color system, variables, sensors...
I spent about four months
learning/experimenting with lua until I discovered arduino and C++.

I am now 14 and have been fascinated with robotics and learned java and dos since.

Just found out a new experience.

I could mention so many libraries and frameworks but im gonna go with arduino.

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)

Looks like im going to have a fun December

In the land of Kangaroos you can claim education expenses directly related to your profession on your tax return. I am developing a plug-in for X-Plane. Do you guys think I can claim costs of my flying school as "education to better understand flight characteristics so that my plug-in works better"?

For anyone who's interested, I'm building a six pack using round LCD displays and an Arduino

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.

Code works yesterday with the hardware but but doesn't work today (ﾉꐦಠヮಠ)ﾉ, they only work when they want

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.

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?

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)

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..

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.

Failing point of surprisingly a lot of interviews:

“WhaTs An ArDuiNo??”

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...

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 :)

CNC finished...
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?

Hey guys.
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 :p

@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 pic

My project just went from "we can use one of those arduino boards, they are cheap and easy to use" to "we need a mass storage solution for that, maybe we can buy a shipping container and put it down on a nearby field as an on site storage". I love the things I would do if I had the resources for this kind of project!

First I helped her with coding the Newton-Raphson method in Python (she has background in Mechanical Engineering).

Later I introduced her to the Linux world and she was amazed with the system responsiveness.

Now I am helping her with learning C (she is programming to Arduino but some concepts are hard for her because Python was her first language).

We are together for 4 years and going on.

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 ?

Python taking over IOT now!!!! #python future

That feeling when you spend 2 hours debugging circuit + code, to find out that the arduino had gone loose in the breadboard...

So the new Arduino Portenta h7 is programmable in JS. Some people just want to watch the world burn!

My morning.. Two days of packages... 40 packages left

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....

#arduino #led matrix
Hey guys.
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.
I'm astowned.....

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 working

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?

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 one

Hey guys
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?
Thanks

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 excited

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. :)

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!

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 you

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?

• Learn Tensorflow
• Learn C
• Learn Java
• Start working on my Arduino projects

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).

I thought It was an arduino app :/

Not a bad idea at all!

OpenCV-controlled Arduino rover

Niceeee.
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 lol

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.

Magic!
When life gives you lemons, don't do a lemonade. Do an arduino program and play!

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?

Arduino :)

Hey guys.
I've been using instructables a lot for arduino tutorials. Do you guys know other sites like that?

How to spend more time writing docs then code?
15m = doc
1m = code

life.c:22: ProjectOverloadException

They said they make their coffee with ****** Arduino !! So I went back to check out the machine. Not what I expected....

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.

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.😑

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... Fml

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.

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 :(((

I'm probably getting Raspberry Pi 3 b+ this Xmas. What are some basic things to learn about it before I start using it? Are there any good beginners guides? I programmed Arduinos, so I kinda understand hardware, but software seems different than on Arduino.

OH MAN it feels so fucking good achieving something with electronics, especially because I have a really hard time learning it by myself

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
