Todo

• Improve this readme.
• Improve the wiki.
• Add an hardware check to the boot sequence.
• Possibly simplify the scripts

• Raspberry Pi: main board
• Arduino: for I/O management on some coponents

General workflow

1. When the raspberry is turned on, it automatically boot up every scripts.
2. Whenever people shouts for long enough, a photo is taken and given a random name
3. Said photo is saved in the to_crop folder
4. The crop_watch script crops this photo, use it to make slides to show the result on screen
5. The photo is shown on screen and the user is given the choice to print it or not
6. loop back from 2
