Firstly grieve if my English is pathetic, I'm franaçais.
I just present my project pneumatic cannon.
It has the peculiarity of being automatic, semi automatic, and burst 3coups.
He pressed a quick exit controlled valve, a valve 3/2 NO, an arduino uno, LCD 16 × 2caractères and some electronic components.
Here are some quick assembly modeling exit valve and distributor:

For the prototype, the arduino uno, LCD and components will be on three printed circuit parralèles like this:
