Hi there
I'm looking to build a project, but need something that emits a signal, but more importantly another device that picks up this signal and will beep at a faster rate as you get closer and closer to the source.
Is there anything cost effective that would allow this? Or is this way too complicted for a small project idea.
Cheers
Colin
