Hi. I want to control volume of my home made amp(2x100W). How can I do this with Arduino Mega? I want to add an LCD with IR Remote. I have already made a program to control an LCD and to change brightness of display, to change contrast and to change volume. I can also change input and output with my program. Here are sources if you want to do same thing smiley-grin :

Main code:
Functions file:
LCD code:
(you must download all files to make it work)

Thank you for your help. I hope you enjoy my code!
