1. Introduction

• The main aim of this project is to design an SMS driven automatic display notice board which can replace the currently used programmable electronic display.

• The message to be displayed is sent through a SMS from an authorized sender.

• The GSM receives the SMS, verifies the sender’s mobile identification pin(MIP) and displays the desired information on LCD.

Summary of related work

• GSM based Airport automation:- This project is used in airport at the time of departure of the flight. Using this project, pilot sends request to the base station, if there is no aircrafts on the runway then base station will send landing permit message to the pilot using GSM.

• GSM based automatic meter reading system using ARM:- The service provider for energy still uses conventional methods for getting the energy consumed by individual costumer. The proposed system automatically reads the energy consumed and sends it to the service provider using the existing SMS.

Comparison of our work with related work

• Both are GSM based project with microcontroller as the controlling unit.

• Use of Short Message Services(SMS) is common in both.

Preamble of the proposed work

• The main aim of the project is to construct a SMS driven electronic notice board which will replace the current programmable notice board.

• To update the notice board remotely and instantaneously.

Architecture

Description of the working of the project

• GSM is connected to microcontroller and microcontroller is connected to LCD display.

• Power supply is given to GSM and microcontroller.

•System is password protected.•So authorized user can send the SMS in this format <password><message body>#•Admin can chance the password(SDMC)

•The SMS must be sent to the valid number which is present in the GSM modem.•GSM receives all the SMSs sent to its valid number and forwards it to microcontroller

•Microcontroller receives the message from GSM and stores it in a buffer and deletes all the messages in the GSM and keeps waiting for the GSM to send new message.•The stored message in the buffer is verified for first 4 character password.
