Hello everyone. I'm not good at this stuff..that's why I came to this forum, very maybe I can find a solution here. I have this triggerable mp3 board that triggers a sound when connected via ground or 'ground pulse'. I want to know if there is solution to hook this thing up on a few switches that I already installed. Actually I need to reconnect all the switches and hook them seperatly trough the board to make every switch work...is there any other solution so I can trigger an audiofile without totally rewire the switches?
