PROJECT DESCRIPTION

The project is designed to use a TV remote as a cordless mouse for a computer to facilitate the user to operate a PC sitting  (over certain distance) away from it.

A typical TV remote sends coded infrared data, which is read by an IR sensor interfaced to an 8051 family microcontroller. The data received by the microcontroller is sent  to the COM port of the PC through a level-shifter IC.

This IR code is an RC5 code as followed by some manufacturers. A Software named PC remote is used on the PC that recognizes data received from the microcontroller through the COM port and performs required operation.

Designated numbers on the TV remote are used to perform up - down, right - left cursor movement. Features like left click and right click of the mouse are also used with the TV remote.

Furthermore, this project can be enhanced using Bluetooth/ RF technology to overcome the traditional line of sight communication drawbacks of the infrared type.
