Reason:Add code tags
copied entire code to repl and got this if it's any use
Traceback (most recent call last):

ImportError: no module named 'platform'
code.py can't go wrong as its just copy and paste from the adafruit web page copy link is provided. same as I did with the simpler display code. did it over several times. working with mu and circuit python makes that part easy but I don't have any coding skills
