REMOTE CONTROL FOR PC

The system of remote control for PC available in the market is usually found
at a high cost. The project is carried out in delivering a low cost PC remote control
system by only designing the receiver. As for the transmitter, the available TVremote
control can be used in integration with the system. The primary objective is to come
out with an infrared receiver which is able to detect the signals received and send the
signal into the PC through serial communication port. The infrared receiver is
designed based on PIC16F84A microcontroller. The infrared receiver is embeddedto
enable the receiver in sensing the presence of infrared signals. The cores of the
project are the applications of electronic fundamentals in circuit design and software
development using C in delivering the receiver functionality. The graphical user
interface is designed using Microsoft Visual Basic as to provide the means of
interfacing between the user and the PC through the utilization of infrared remote
control system. The project methodology stresseson the researchand analysis, circuit
design, circuit modeling, microcontroller prograrnming, circuit fabrication and
finally, designing the interfacing software. The end system comprises of the hardware
for receiver, universal remote control and interfacing software, which can be utilized
in controlling several PC applications.
