Description: This new revision of the SparkFun MP3 player shield retains the awesome MP3 decoding abilities of the last version but adds the storage functionality of the SD card shield. Now you can pull MP3 files from an microSD card and play them using only one shield, effectively turning any Arduino into a fully functional stand-alone MP3 player! The MP3 Shield still utilizes the VS1053B MP3 audio decoder IC to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis.
The VS1053 receives its input bitstream through a serial input bus (SPI). After the stream has been decoded by the IC, the audio is sent out to both a 3.5mm stereo headphone jack, as well as a 2-pin 0.1" pitch header.
Note: Please refer to the Line Out document below for important information regarding connecting this shield directly to an amplifier.
Checkout the great MP3 Player library that Bill created (and fixed some of our programming bugs!). Bill, we owe you a beer.

Haven’t started my MP3 project yet. Still completing my Android game called Polgonroids (like asteroids only more fun). Have the prototype up and running but more development to come. I am currently completing a Masters in IT and use projects like this to test myself against complex logic and to keep up to date with programming. The MP3 shield will be used in conjunction with blue-tooth technology to build a high quality portable wireless speaker system which can be completely controlled by a typical android phone (like a PILL but much better, No shitty cables or audio). This means writing, deleting and streaming MP3 files and adjusting all sound properties. The speaker system will be very “arty” and perhaps decals can be specially designed to suit individual tastes. I will let you know how I go. I see great potential in your product for fun individual projects. So easy to imagine possibilities.
