How would I go about making an 'item locator'? (like a remote control finder/key finder)
How would I go about creating an 'item locator' such as one used to find a remote control or car keys. I've been interested in setting up a system for all the things I keep in my storage area so that they are easily found by pressing a button on a panel or 'base' and then having it locate the actual item (which will start beeping/flashing, or what have you). I'm curious as to how these typically communicate with each other since I'm a beginner in electronics.?
