I was able to hook up my Arduino to make the servo-motor work. It was pretty straightforward. Using code from Steven Litt, I was able to hook up a piezo speaker, and then an amplified speaker, and get some sweet digi-noise out of the circuit. Using a photoresistor and a potentiometer, the user can moderate the pitch.
