/* Play Melody
* -----------
*
* Program to play a simple melody
*
* Tones are created by quickly pulsing a speaker on and off
*   using PWM, to create signature frequencies.
*
* Each note has a frequency, created by varying the period of
*  vibration, measured in microseconds. We'll use pulse-width
