This is a way too long tutorial on how to play medium quality audio files on an Arduino. I remember myself starting and what was supposed to be fun development, often times proved to be frustrating error checking. I wanted to make this explanation as complete as I could to help out everyone who might run in to some trouble. More importantly though, I am hoping to help build a more general understanding of the concepts behind this project. Learning how and why it works is vastly more important than just to play a song.
---------------------------------------
You can hear popping sound out the beginning and the end of playing. This is known by the TMRpcm developer and supposedly solved in most cases. See the discussion here:
