 * 
 * INSTRUCTION: Hook up Pin 10 to the positive side of a buzzer or a microphone, hook up 
 * any resistor to the negative side of a buzzer (to limit current & volume & to protect the pin), 
 * and then connect the other end of the resistor to ground pin. Upload the sketch and enjoy! 
 * 
 * Don't have an Arduino right now? No worry. You can test it vitually on my TinkerCAD circuit:
