/*
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
