Hey Arduino Forum.
I want to work on a project where my arduino knows where it it located in a space. I was wondering if it would be possible to setup a few radio signal emitters/receivers and sense distance. Is there a type of sensor or breakout board that I could use? I know that acoustic distance sensing, but I need something that isn't audible (which is why I thought of RF).
The total "volume," isn't probably going to be more than 3x3x3 metres.
Any ideas or guidance is highly appreciated. Thanks!
