4x4x4 LED cube with Arduino Uno and 1sheeld

/*

This code uses 1Sheeld and an arduino Uno board to control a 4x4x4 LED matrix using 
  the microphone of your smart phone.
 
 The circuit:
 * 64 LEDs form a 4x4x4 cube connected with the 1Sheeld and arduino board  
 * The coloumns control pins are connected to digital pins  0 to 13 and analogue pins 
     A4 and A5
 * The layers control pins are connected to analouge pins  A0 to A3.
