This document describes a GSM-based electronic notice board display system. The system allows an administrator to send notices and update student information via SMS from a PC or mobile phone. When an update is made, a confirmation SMS is sent to the administrator and a message is displayed on the LCD notice board. Students can also send an SMS to receive notices and information like timetables, marks, or holidays. The system uses an ARM7 microcontroller, GSM module, LCD display, RS-232 interface, and power supply. It has applications for educational institutions to easily communicate information to students and parents through SMS.

Required information will be updated by the admin Using pc or mobile Admin will receive a confirmation SMS when the message is displayed on LCD Same time a MESSAGE DISPLAYED ON THE NOTICE BOARD will be sent to all students Student have to send NOTICE to get the information through SMS Similarly student can get information regarding TIME TABLE,IA MARKS,HOLIDAY or other require information
ARM 7 GSM MODULE DISPLAY UNIT RS 232 INTERFACE POWER SUPPLY
ARM stands for advanced RISC machine 32-bit processor High code density Conditional execution Variable cycle execution for certain instruction Good speed/power consumption
GSM stands for global system for mobile communication Uses FDMA-TDMA technology Sends and received SMS Monitor the signal strength Easy to integration to RS 232 application
LCD-Liquid Crystal Display Ability to display numbers, characters and graphics. LCDs are economical and easily programmable
Provides simplest connection between PC and ARM The DB9 connector is mainly used for serial connections, allowing for the asynchronous transmission of data as provided for standard RS-232 (RS-232C). simplest connection between a PC and microcontroller
ARM operating voltage is +9v GSM operating voltage is +12v Block diagram of power supply
Embedded C Keil u vision Flash magic
Educational Institutions and Organizations. School College Coaching institute Railway Station.
User friendly. Eliminates use of printer. Long range. Faster means of transferring of information.
Dependent on signal strength. Volatile memory used for storing the message.
The display boards using GSM can become major communications medium for mass media. This project saves time, energy and is user friendly. Cost of printing and photocopying is also reduced Information can be given to a large number of people from our fingertips. Thus we can conclude that this project is just a start, an idea to make use of GSM in communications to a next level.
