/*
 * buzzer2: for the Orangutan LV/SV-xx8
 *
 * Uses the OrangutanBuzzer functions to play a series of notes on the
 * Orangutan's buzzer.  It uses the OrangutanPushbuttons library to
 * allow the user select which melody plays.
 *
 * This example demonstrates the use of the play() method,
 * which plays the specified melody entirely in the background, requiring
 * no further action from the user once the method is called.  The CPU
 * is then free to execute other code while the melody plays.
