Versatile Economical Message Transfer

This project work is to design a system which will help us to transmit text message on LCD display and audio message to the speaker using a free ware wireless protocol. This system does not use any of internet device or GSM based protocols. Here the basic and essential concepts of radio communication is utilized to create a wireless communication channel between Computer-LCD display and computer/microphone-speaker. Here a computer is placed at the transmitter side from where the message is to be transmitted serially through USART protocol. ARDUINO microcontroller and low power 2.4GHz transceiver is used as interfacing unit between the transmitter and receiver side. On the receiver side a LCD display unit and a speaker is used for displaying the text and audio messages.
