/*
Buzzer
The example use a buzzer to play melodies. It sends a square wave of the
appropriate frequency to the buzzer, generating the corresponding tone.
The circuit:
* Buzzer attached to pin39 (J14 plug on Grove Base BoosterPack)
* one side pin (either one) to ground
* the other side pin to VCC
* Note:
This example code is in the public domain.
