/*
  plays melody and fades led based on analog input
  changes from sketch 3:
  * had to change led and speaker pins due to PWM timing issues
    http://arduino.cc/en/Reference/Tone
  * moved sensor and LED code into the for loop so that it is updated as the song runs.  makes program more responsive.

  circuit:
  * piezo speaker on D9
  * potentiometer with center wire to A0
