Hi all, I'm new to the arduino developers community and am trying to figure out what direction to take for an upcoming project.
The project entails developing fake suitcase prop bombs for a paintball park. Each of the 3 props would feature an activation keypad that a user would need to specify to 'arm' the prop. Once each of the 3 props are armed, an audible ping sound would play over all 3 different props over the built in PA speakers.
My question is, how would I go about connecting these devices together wirelessly? Thanks!
