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