Abstracts: The outline of the project is that the text message typed using a computer keyboard attached to a micro controller to be sent, is encrypted by using an appropriate program with LCD display and then the encrypted message is transmitted through wireless using Radio frequency transmitting Module. At the receiver end the signal is received by the RF receiver module and the analog signal is converted to digital form. It is fed to another Micro controller where it is decrypted by the program and the message is then displayed over the receiver LCD display.
