Hi, I am pretty new to Arduino.
I have code that worked successfully with my old Arduino board about a year ago. Then this year I bought two new ones, but I couldn't successfully run through all the lines in my code. (I can successfully upload my code to Arduino board)
Does anyone know the potential problem with it?
Is it possible that the same code that works for the old Arduino Nana 33 BLE, but not working for the new ones?
