DESIGN AND IMPLEMENTATION OF REMOTE CONTROL DOOR SYSTEM
ABSTRACT The paper presents a simple design and implementation of a remote control door. It enables the user to control the door using remotefrom approximately10 meters away. The remote transmits a tone using an infrared light-emitting diode. This tone is decoded by a receiver, since the receiver only switcheswhen the tone is received. The system was broken down into simplerfunctional blocks namely; infra-red transmitter, infra-red sensor, signalamplifier, control logic, sampler, ...
