use a footswitch to activate MP3?
I am attempting to set up a foot pressure switch to activate an mp3 player for an art exhibition. I wired up the footswitch to to close the circuit when pressed between the speakers and the mp3. Unfortuneatley it only closes half the circuit so the other half remains open giving a lot of hissing sounds. The idea is that the mp3 remains on and playing but that when the pressure swicth is stepped on it closes the circuit so the music plays. I need to find a way to break the entire circuit when the mat is not stepped on. Any ideas how to achieve this?
