Debug how to print out to console

how can i print out to console some variabels?


You will also need Serial.begin(9600) in your setup(), and a tool to read what’s written (the Arduino IDE has a serial console tool).

Does it have to be 9600 baud? I tried 115200 bps once, and very bad things happened.

Same here, tried something else, bad things happened. I stick to 9600 since. :slight_smile:

Thx it works just fine.
Finally figured out the flags of the keys :smile:
