If you are looking for a challenge, or wish to learn some coding basics for Raspberry Pi while setting up your photo booth, we encourage you to follow the Pi Foundation's instructions at their website here.
This tutorial is a remix of the Pi Foundation's original learning resource. We added additional buttons to ours, mixed up the overlays, and changed a few things around in the code. The Facet Photo Booth operates without a mouse or keyboard, making it a good choice for large groups of people (especially children), or for those who want a sleeker look. The Pi Foundation also created neat housing for their booth, and includes instructions for those who wish to use a touchscreen LCD with their photo booth.
Now, on to the instructions!
