You can help me, I can not make it work

I’m reading this on a phone, so it’s difficilt to see the full structure of the code. However, I think that what you’re trying to achieve in this bit of code is to call the checkPhysicalButton function on a regular basis with a timer. However you’ve not done that and instead you have declared the checkPhysicalButton twice.

Some comments in the code would make it more readable, and some Serial.print statements would help you know when a particular piece of code is being executed.
