00011  Arduino MP3 Shield MP3Player_UI
00012  2010/10/10
00013  This program comes from http://mbed.org/cookbook/VS1002-MP3-Decoder and is the work of xshige.
00014  (Very small modification done to fit latest libs)
00015 **more small modifications done to add a small user interface via LCD screen, rotary encoder and dipswitch,
00016 see http://mbed.org/cookbook/MP3-Player for more information on pinout for these devices, these UI mods by (mpetersen3 and kbuck3)
