do something like the space marines gun in alien, or the MA5 from Halo games, that count every BBs that passes through a silencer, print it on a screen, then reset when we load a new magazine.
It should have other options like a compass, a clock, ... to put info on the screen.
The objective is to make an airsoft gun smarter.
Optionally, it would be cool to add some functions like a link between a esp32-CAM and the screen to technically cover 2 lines at once
