Hello Fello Arduino enthousiasts.
I'm encountering a problem (or lack of knowledge) regarding pins 2 and 3.
I'm experiencing the following:
I have started creating a button box.
On this box I have a button connected to pin 2 and another button connected to pin 3.
When i press button 2 an signal is also measured on pin 3.
I suspect this has something to do with PWM as this problem is also observed for pins 5,6 and 10,11.
The board I am using is a pro micro.
Is this something that can be disabled with code? have I done something wrong or is this simply part of the board and pin 2 and 3 cannot be used simultaniously?
Thank you for taking time to help me out!
