ABSTRACT
The paper presents a simple design and implementation of a remote controlled fan regulator. It enables the user to operate a fan regulator from approximately 10 meters away. The remote transmits a tone using an infrared light-emitting diode. This tone is decoded by a receiver, since the receiver only switches when the tone is received. The system was broken down into simpler functional blocks namely; infra-red transmitter, infra-red sensor, signal amplifier, control logic, sampler, control stepper, output control logic, load and display unit. Details of each subunit are described in the paper.
