Input Devices : Remote Controls

A remote control is used to operate a machine from a distance. Remote controls are used with consumer devices such as televisions and hi-fi music systems and vehicle locking systems.

Remote controls have a small keyboard on them with buttons that relate to the particular functions of the machine that is being controlled. When the buttons are pressed a signal is sent from the remote control to the machine, usually by infra-red light or radio signal.

It is more convenient to be able to operate a machine remotely than to have to move to the machine to use it.
