I have an Adafruit Music Maker Shield attached to an Arduino. I want to press a button and have it play an audio track as soon as the button is pressed. Five seconds into the audio track I need it to turn a pin on HIGH. The audio track is 15 seconds. After the audio track has finished playing I'd like Pin 2 to return to LOW and have the ability to repeat the process once I press the button again. Pin 2 is the pressed down button signal and Pin A0 is going to a relay.
