Hello folks, I am here with a simple and interesting arduino project, RF based wireless Message Transmitting system. By using this system you can feed the data to be transmitted serially to the transmitter from your PC. The project mainly consisting of a Transmitter and a  receiver section. Transmitter is made by Arduino Uno board and receiver is made by Arduino Mega2560. The communication between transmitter and receiver is through RF, Amplitude Shift Keying.
