Hi ! Im searching for a controller board, to play a servo sequence with min 4 servos, by line input signal. The object has to move when sounds from a mp3 player are playing and stop, when the track is over. I used pololu mini maestro, but havent found a way to realise this projekt, yet. Any experiences ?
You could do this using an arduino with an Adafruit sound board. Have the first bit of code trigger the sound board using a transistor then write your code to move the servos for the allotted playback time.
