Detailed Description
Plays beeps and music on the buzzer on the 3pi+ 32U4.
This class uses Timer 4 and pin 6 (PD7/OC4D) to play beeps and melodies on the 3pi+ 32U4 buzzer.
Note durations are timed using a timer overflow interrupt (TIMER4_OVF), which will briefly interrupt execution of your main program at the frequency of the sound being played. In most cases, the interrupt-handling routine is very short (several microseconds). However, when playing a sequence of notes in PLAY_AUTOMATIC mode (the default mode) with the play() command, this interrupt takes much longer than normal (perhaps several hundred microseconds) every time it starts a new note. It is important to take this into account when writing timing-critical code.
