One simple solution is that each item would have to know it’s location (GPS?) then communicate with the other devices over wireless (probably WiFi). You could do all of that in a mobile phone app then have the app communicate with a worn device using Bluetooth LE. That’s also the level of a final crit project where you’ve spent the semester building each element in assignments and crits.

I sent you an email but I leave a comment here just in case.

I have a technical question about Arduino for Critique 1 Assignment.

The problem I am focusing on is when people go to a concert where there are a lot of crowds, it is difficult to find friends because it is so noisy and smartphones usually become out of service. So, I want to design a pair of necklaces (or bracelets) with LEDs, which become brighter (or change colors) when they are closer and become dim out when they are further, by detecting each other’s proximity.

I tried to find a component to make this feature in Arduino, but could not come up with any solution yet. Could you recommend me how could I make this?

Thanks,
Jay
