hi so new to world of anything electronic. i want to basically trigger the l and r of a stereo audio separately and have the second waveform sync up with the first no matter the time it was triggered. each wave form would be triggered by its own motion sensor. i believe this to be a question about programing and code question. hardware (arduino uno & basic sparkfun mp3 player shield (w/ VS1053B)
I'm not quite sure what you mean by 'sync up' (are both channels outputting the same waveform?) but if you start both streams at the same time you could just use the channel volume controls to mute either stream when you didn't want it?
