Good evening,
im new to arduino. Here i'm trying to make a oled menu controlled with 3 buttons, also i'm using a Arduino UNO.
The code works so far, but after 5 minutes or so, it freezes.
I tried a couple of methods to stop it from freezing, without success.
Does anybody know what could be wrong with my code?
Thank you!
