I’m working on an LED project for a friend. It would be very helpful if I could make it react in ANY way to his electric guitar. Fast/slow would be best but obviously that would be pretty complicated. So I’m just looking for anything to get cues to make the LEDs react. My goal is to also get it to self calibrate every few seconds so that it can get cues whether the playing is quiet or loud. But for now, I would really appreciate any advice on how best to do this. I realize I cannot expect it to synchronize perfectly like a lighting display at a concert, I’m just looking for cues to trigger the LED’s to change speed and patterns.
ANY info on this subject would be great, I’ve only just began to look into it.
I also was wondering how to most efficiently connect the guitar to the arduino. I wasn’t sure if it would be as easy as simply connecting the line to an analog input.
