  # The Thumb Joystick is an analog device that outputs analog signal ranging from 0 to 1023
  # The X and Y axes are two ~10k potentiometers and a momentary push button which shorts the x axis
  
  # My joystick produces slightly different results to the specifications found on the url above
  # I've listed both here:
