FYP: Playing with Arduino
So I've been having a play with the technology I need to make this work. Using an Arduino, servo & potentiometer I devised a digital controller for my amplifier. Using the input from the potentiometer mapped to the output of the servo I can control my amp volume. The theory involved in this is a proof of concept - if I can prove I can control volume this way, then it's a stepping stone towards controlling it remotely.
