/*
  Example 05: Piezo Buzzer (Sound)
  Sidekick Basic Kit for TI LaunchPad

  Play birthday tune through the buzzer, demonstrating the
  buzzer tone() API and pitch/tone (hence music) generation

  Hardware Required:
  * TI LaunchPad
  * Breadboard BoosterPack
  * Breadboard
  * 2x Jumper wires
  * Buzzer

  This example code is in the public domain.
