I've made a digital-shooting range for IR rifles.
It has 5 targets (1 rgb led + 1 IR receiver) connected by wire to an arduino mega.
The basic of game is actually simple: the board choose a random target, light in red the led, when the shooter hit it, the led became green and arduino choose another target.
There are some other features (choose of game, time, speed etc) but the core is that.
It will be possible to convert in wireless, using RF modules?
My idea is one base board that control 5 boards, each one with own RF module.
I don't pretend to let you say me how do it, but at least know if it is possible.
Could it work like the wired one?
