# Code below is a simplified version of the code found here

# https://www.waveshare.com/wiki/Joystick_for_micro:bit

# but still a lot to it.

# On the one I was trying it with the push button on pin 8 didn't work

# so I have commented it out below. 

# The A and B buttons on the micro:bit are not used in this program
