Hello, My name is Javier and I am an Arduino programmed beginner.
I have a program, which works perfectly in Arduino uno and Nano, but does not work in Arduino Mega. I understand that they have different processors and different pins. This programming got to dump it to arduino Mega, but it does not respond to any of the programming.
About programming: It is a projector of a musical synthesizer, which has inputs (buttons) (musical notes), up button and down button (to change the sounds), lcd screen to see the name of the selected sound, and audio output .
Would someone tell me that I have to change to make it work in mega? I am desperate and my programming knowledge is basic
