Quick Draw Duo played on two Circuit Playground Bluefruits with external audio.

This project is a variant of the Circuit Playground Quick Draw game for a pair of Circuit Playground Bluefruit (CPB) boards using CircuitPython. Bluetooth Low Energy (LE) is used to exchange information between the boards. This means you can play the game wirelessly!

An additional CircuitPython program can be used to measure and compare visual and auditory reaction times. This can run on either a Circuit Playground Express (CPX) or CPB board.

Thank-you to Carter Nelson for the original game and Megan, Izzy, Elsa and Matilda for help in testing the new game.

The two CPB boards require the latest 5.x version of CircuitPython.
