/*
 Galileo Sequencer
 This sketch is used for a demo of the Intel Galileo board. When it was launched in Rome Maker fair 2013, 
 we made a sequencer based on Galileo, SparkFun MP3 shield and the sketch ReadMP3fromSD originally created 
 by Nathan Seidle.
 
 The sequencer has 2 knobs, 4 buttons and 8 leds on its interface. When activated, it loops through and
 plays 8 segments of sound samples repeatedly. At the mean time, the LEDs will light up according to which
 segment you’re listening to. You can use the buttons and knobs to customize and add creativity into the sequence.
