This guide will show you how to play the reaction game in the video, using PiFace CAD.
git clone https://github.com/thomasmacpherson/catchCAD.git
Move into the newly created folder
Run catchCAD with the command
You will see the PiFace CAD's backlight turn on and two plus symbols will appear.
The aim of the game is to press the leftmost button on the PiFace CAD when the two symbols align. The moving symbol will get faster and faster until you fail to hit the button at the correct time.
When the game is over your score will be displayed.
You will be given the option to play again. Move the rocker switch left or right to select your response and press it in to enter.
