This document describes a remote notice board implementation using GSM communication. The system uses an 8051-based microcontroller interfaced with a GSM modem and LCD to display messages sent via SMS. It allows users to remotely change display messages in real-time. When an SMS is received, the microcontroller updates the LCD according to the message. The system provides low-cost, automated operation with low power consumption for remote advertisement displays.

REMOTE NOTICE BOARD IMPLEMENTATION USING GSM COMMUNICATION
ABSTRACT
AIM:
THE MAIN OBJECTIVE OF THIS PROJECT IS TO DEVELOP AN EMBEDDED
SYSTEM, WHICH IS USED FOR SPONTANEOUS ADVERTISEMENT USING GSM
TECHNOLOGY.
IMPLEMENTATION:
THIS PROJECT IS IMPLEMENTED 8051 BASED AT89S52 DEVELOPED BOARD
INTERFACED WITH GSM MODEM AND LCD FOR DISPLAYING THE DATA.

DESCRIPTION:
NOW A DAYS EVERY ADVERTISEMENT IS GOING TO BE DIGITAL. THE BIG
SHOPS AND SHOPPING CENTERS ARE USING THE DIGITAL MOVING DISPLAYS
NOW. IN RAILWAY STATION AND BUS STANDS EVERYTHING THAT IS TICKET
INFORMATION, PLATFORM NUMBER ETC IS DISPLAYING IN DIGITAL MOVING
DISPLAY. BUT IN THESE DISPLAYS IF THEY WANTS TO CHANGE THE MESSAGE
OR STYLE THEY HAVE TO GO THERE AND CONNECT THE DISPLAY TO PC OR
LAPTOP. IF THEY WANT TO DISPLAY MESSAGES ABOUT SOMETHING CRUCIAL
WITHIN 5 MINUTE, THEY CAN’T

HERE WE ARE DESIGNING A NEW DISPLAY SYSTEM WHICH CAN ACCESS
REMOTELY, WE ARE USING THE GSM TECHNOLOGY TO ACCESS THE DISPLAY’S
IS ONE OF THE NEW TECHNOLOGY IN THE EMBEDDED FIELD TO MAKE THE
COMMUNICATION BETWEEN MICROCONTROLLER AND MOBILE.
THIS PROJECT IS A REMOTE DEVICE WITH GSM MODEM CONNECTED TO IT,
SO IF THE USER WANTS TO DISPLAY SOME MESSAGES, HE WILL SEND THE
MESSAGES IN SMS FORMAT. THE GSM MODEM WILL RECEIVE THE MESSAGE AND
THE MICROCONTROLLER WILL UPDATE THE DISPLAY ON THE LCD ACCORDING
TO THE MESSAGE.
THE SYSTEM USES A COMPACT CIRCUITRY BUILD AROUND FLASH
VERSION OF AT89S52 MICROCONTROLLER WITH A NON VOLATILE MEMORY
PROGRAMS ARE DEVELOPED USING EMBEDDED C, COMPILED USING RIDE
TOOL. ISP IS USED TO DUMP THE CODE INTO MICROCONTROLLER.
SOFTWARE:
EMBEDDED ‘C’
RIDE TO WRITE CODE
ISP TO BURN THE CHIP
HARDWARE:
AT89S52 BASED OUR OWN DEVELOPED BOARD
