Abstract
In this competitive world human cannot spare his time to perform his daily activities manually without any fail. For giving any power point presentation most of the people need help of another person to move the slides or he has to go to the system and change the slide which creates lots of disturbance in his presentation. To avoid all those things this project can be useful as we can operate the presentation slides by the remote. It has laser light indication also which makes your presentation more meaningful and user friendly.
This project gives the best solution for time wastage and efforts. Also the manual operation is completely eliminated. The presentation can be operated using RF without actually going near the system.
The RF receiver takes the transmitted data and sends to the controller which is connected to PC. The mouse is controlled by the commands given by the controller through the .NET applications. A laser light is provided with the remote through which we can point out the things which are being explained.
