I need some help or advice for my problem:
When I plug in my Arduino UNO Wi-Fi rev 2, my computer gives an error 43 and an unknown device.
Also, the "ON" LED lights up and the "L" LED blinks something fast (first half second or so); no RX or TX lights.
What I noticed about the earlier program (long time ago) -measured with a blue LED and potentiometer- is that the D11 switches on and off at a defined A5-value.
My thinking way is that I tried to do something with that, and I blasted the Arduino software away? Or trying to make I2c connection, but failed?
Can this be a thing, or is it a hardware problem? (Arduino always plugged in without other things on it!)
What I already have done:
Plugged the board to the 9V source and felt if anything gets hot, NOT!
Video about code 43 and how to fix it 100%;
Reinstalling the library in Arduino IDE;
All these things weren't a solution, because "code 43" keeps coming
