/*
  Simple Audio Player for Arduino Zero

 Demonstrates the use of the Audio library for the Arduino Zero

 Hardware required :
 * Arduino shield with a SD card on CS4
 * A sound file named "test.wav" in the root directory of the SD card
 * An audio amplifier to connect to the DAC0 and ground
 * A speaker to connect to the audio amplifier
