I got a magical IR remote!
When i press and hold that button to dim down my RGB LED strip, my Bluetooth speaker turns on!

I made internet radio player with raspberry pi. It uses IR remote controler and also play music from my collection. Pi is really usefull device. So happy.2 -
2nd post progress of this project https://devrant.com/rants/9985730/...
I went to shop to buy missing ir diode and bluetooth for arduino.
Launched arduino today with ir receiver and I managed to reverse engineer protocol.
Turns out it’s just NEC remote codes.
I used this library https://arduino.cc/reference/en/... to easily send and receive ir signals.
Everything took me whole day cause I’m rookie in hardware.
I can now remote control medion md 19500 using arduino.
Next step is to make it riding itself.
I need to measure speed and turn angle with error rates.
I will probably use pen and paper and let vacuum cleaner draw angle for me and after that I will use the most modern, accurate and cheapest angle measurement tool that is protractor - school welcome back
Speed can be more complicated and need another external complicated tool that is tape measure and a clock.
I also bought second robot because I got this stupid idea to allow people to control robots using internet.2 -
I bought medion md 19500 vacuum cleaner refurbished for about 74 usd, it can be controlled using ir remote
I disconnected vacuum top and it’s still working so my plan is to use arduino instead of attached remote to control robot
I can try to identify where ir sensor is to directly connect to it, but don’t know if my skills are enough to do it.
edit:
to compare, roomba create 3 costs 450$ and I can buy this vacuum used without remote for 38 usd24 -
So, I need to figure out what ir protocol a controller board uses. I know how to do it with a remote, but how would I do it with the board? Can I reverse engineer the ir reciver to find it's protocol?10
