How best to move a servo to music?
Hi All! I have a quick question, I want to move a servo in time with music and was wondering how best to do that with an arduino. I found someone on Instructables who made a talking skeleton open its mouth when the volume of the music rose above a certain point but just remapping the analog in signal from my wave shield is not moving the servo as smoothly as I would like, it just sort of jitters around. I guess this makes sense as the voltage changes quite a bit to create an audio wave form. I have a wire from R7 on my wave shield plugged into an analog port. Would the MSGEQ7 chip be the best way to accomplish my goal or is there another way? If anyone is curious I am attempting to move the arms of a portal turret in time to the turret opera. Thanks for your time,
