Introduction
The mp3 player serial is a cheap solution to add sound to your project, otherwise you could get a shield from Sparkfun or Adafruit which would cost more.

Files
I couldn't find much information about this device or the vendor didn't give me a datasheet or sample arduino, so after I google for a while, I found all of it.
Datasheet and Sample Arduino
Wiring
The wiring is pretty simple, connect the serial communication to the Arduino and 5V is required.
In my project I add a 3W amplifier just in case the sound wouldn't be too loud but otherwise you can avoid it.
Commands
The datasheet confirm that there are these commands available for this module:
