Code below is a simplified version of the code found here https://www.waveshare.com/wiki/Joystick_for_micro:bit
There is quite a lot to it . The A and B buttons are also running in this program but not shown in the above video. The joystick also has a built in push button though that didn't work for me. Not sure if that was a problem with the code or the joystick. I'll test it with another one when I can and will update this page when I know more.

# 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 also used in this program
