Hi all,
I was hoping someone might be able to help me with a little project. I'd like to build a small proximity detector that can detect (flash an led or beep etc) when a copy of the circuit is in a range of about 10M.
I know this would require a transmitter & reciever running continuously within the same circuit. I presume there would also need to be something that would tell it to ignore signals that are too strong, otherwise it would continuosly detect itself.
I was thinking a small bluetooth-type of device would do the job.
The idea is that a group of random people could each carry one with them, while they walk around in a public place & have to find each other. It's sort of a life based game where players chat online & so never actually see each other until the circuit tells them that another player is nearby.
Thanks in advance
