Distance and direction detector? Answered
What I want to do is build a device that I can hold in my hand that will notify me (probably with an LED) if I am facing the object I want to find, and preferably how far away I am. I can't use IR because if something is between me and the object I still want to know if I'm facing it
I'm not sure what method I would use but I want to build a device that consists of a transmitter and a handheld receiver, I would probably use radio, and the transmitter would have to be very small, (Keychain sized or smaller preferably).
