How do you build a remote controlled device?

Get a transmitter, a receiver, and the thing you want to control.
You haven't stated the kind of device: stationary such as a garage door, or mobile such as a racing car.
You haven't stated the kind of remote: wireless, infra-red, bluetooth or over a wired network.
Your question is too complicated for this kind of Wiki. Go online (or to a bookshop or library) and look for instructions on building remote control devices. Try "Instructables" as your first port of call.
There are also kits available at hobby shops and online that will make the task easier.
