I recently bought a Raspberry Pi Pico WH and a Pimoroni Pico Display. I'm coding my first project with it, using the bones of one of the Pimoroni programs that they start you off with.
I'm trying to make a countdown timer that starts at different times depending on which button you press. I'm getting everything to display correctly, but when I try to introduce a while loop into my code, it breaks after I press the button. (The starting screen still loads fine.)
I'm completely inexperience with Raspberry Pi and only a little experience with python. Can someone please tell me where I'm going wrong? I've tried so many iterations, and it just seems to me like it hates the word while.
