/*************************************************************************
 * This demo uses the BALibrary library to provide enhanced control of
 * the TGA Pro board.
 * 
 * The latest copy of the BA Guitar library can be obtained from
 * https://github.com/Blackaddr/BALibrary
 * 
 * This program can be used to find out the calibration values for each of your POTs
 * on the Blackaddr Audio Expansion Control Board.
 * 
 * USE THE ARDUINO SERIAL MONITOR TO PERFORM THE CALIBRATION
 * 
 * When prompted turn the appropriate POT in the specified direction and
 * enter any character on the terminal input line and press enter to send the character.
