We're nearly there, the code works and i can change which gpio is true or false via the doHAT only problem is when your faced with the on or off options the previous error appears in the shell,
however the on and off also dont scroll so you dont know which is selected it appears like:
Off
>On
Off
you also cant seem to go back once on this screen
Just tried this think thats what you meant but now i get the name 'handle_on'is not defined again
