/*
 Keyboard Test
 
 Check how the robot's keyboard works. This example
 sends the data about the key pressed through the
 serial port.

 All the buttons on the Control Board are tied up to a
 single analog input pin, in this way it is possible to multiplex a
 whole series of buttons on one single pin.

 It is possible to recalibrate the thresholds of the buttons using
 the Robot.keyboardCalibrate() function, that takes a 5 ints long
 array as parameter
