I am still working on this project. Having to recode everything for reasons I don't quite understand. But hey, I found some ways to improve on the coding. It was causing quite a delay to have so many time.sleep commands to get lights to flicker. So enter this article from the awesome folks over at Adafruit. A better way to interrupt and multitask in CircuitPython.
I still have to attach the potentiometer, the speaker, and the IR LED to make this compatible with my soon to be realized laser tag game.
