Network of around 50 devices that can sense relative proximity to each and blink a light with a cadence commensurate to the distance of the next closest node (blinks faster the closer they get).
The idea is to create a game of serentipity where members of the camp can find one another when their path's cross throughout the week - particularly at night.
Range would need to be a few hundred yards radius and would like to use Arduino as our platform.
To solve the issue of multiple nodes traveling in packs we will program the network to treat devices within some inner radius of each other (20 ft or so) as one node.
Ideally would be as low tech as possible and not need to pair with our phone's GPS but haven't found good solution to get proximity from wirelessly connected devices alone.
Party Mode when more than 20 devices are within the inner radius of each other (light blinks like crazy and cycles through colors).
