RF Based Remote control (AT89C2051)

The Project Long Range Remote Control can be used to remotely control a number of Electrical or Electronic Gadgets connected to it. Unlike Infra Red remote control, this Project employs FM transmission and Reception, and hence it can be used for comparatively longer range. Any gadget can be switched on/off by keying the number allocated to it. The Receiver is made up of the famous 8 bit Microcontroller from Atmel. The Microcontroller is used as the Master in the receiver end which is used to control all the devices. It decodes the Signal from the transmitter and control the relays according to the signal. For transmission we are using frequency modulation at the frequency of 433.92Mhz.
