Wireless communication has announced its arrival on big stage and the world is going mobile. We want to control everything and without moving an inch. This remote control electronic notice board is possible through Embedded systems. The use of "Embedded system in communication" has given rise to many interesting applications that ensures comfort and safety to human life. GSM(Global System for Mobile Communication) is globally accessed by more than 212 countries and territories. Global system for mobile communication is optimized for duplex voice telephony. GSM, initially developed for the replacement of first generation (1G) technology, now it is upgraded for second generation (2G) technology and third generation (3G) technology.

MAIN FUNCTION OF GSM BASED E-NOTICE BOARD

1. Using GSM mobile we can send message to any distant located e-notice board from any remote area.

2. By interfacing the GSM modem with mobile phone ,we can send text message from any remote area.

3. GSM MODEM, SIM, LCD(Liquid Crystal Display), microcontroller ,power supply and also some connecting wires are the common peripherals required for developing any GSM based applications.

CONCLUSION

The prototype of the GSM based display toolkit is efficiently designed. This prototype has facilities to be integrated with a display board thus making it truly mobile. The toolkit accepts the SMS ,stores it ,validates it and display it in the LCD module. The SMS is deleted from the SIM each time it is read.
