ACKNOWLEDGEMENT
It is our proud privilege to have Mr. Inderjit Singh as our mentor for this project, GSM Based
Notice Board Using Arduino. He has been an immense help to us since the beginning of the project. He
guided us at tough times and helped us achieve this goal. We are very thankful to him for his help and
support. We would also like to extend our thanks to our H.O.D, Vikramjit Singh for his faith and making
us believe in ourselves. His guidance has been the reason we could complete this project.

ABSTRACT
Notice board is primary thing in any institution or organization or public utility places like bus stops,
railway stations or parks. But sending various notices day to day is a tedious process. This paper deals with
advanced notice board. It presents an SMS based notice board incorporating the widely used GSM to
facilitate the communication of displaying message on notice board via users mobile phone. Its operation
is based on microcontroller ARDIUNO programmed in C\C++. A SIM900A GSM modem with a SIM card is
interfaced to the ports of the microcontroller with the help of AT commands. When the user sends a SMS
via a registered number from his mobile phone, it is received by SIM900 GSM modem at the receivers
end. SIM300 is duly interfaced to the microcontroller. The messaged is thus fetched into the
microcontroller. It is further displayed on an electronic notice board which equipped with LED MATRIX
display interfaced to ARDUINO powered by a regulated power supply from mains supply of 230 volts ac.
CHAPTER 1: INTRODUCTION TO GSM BASE NOTICE BOARD
1.1. Objective
Conventionally there was printed notice board. Which was used to display any sort of the information
but they were not much useful as it was more difficult to change the information periodically and
there was a lot of paper and ink wastage to. Then came electronic notice boards which used LEDs,
with a particular combination to display any sort of information. But we needed to redesign the board
in case to change the information. This project aims at developing a GSM BASED MESSAGE DISPLAY
that will design such a board which will be displaying a scrolling message which is send to the board
via SMS.
1.2. Limitations of existing technology
Currently we rely on the conventional technique of using paper for notices. This is time
consuming method.
This leads to wastage of paper. Renovation of the notice needs a new hardcopy.
All notice boards presently rely on wired electronic systems. One of the major drawbacks
of this design is its inflexibility or its bulkiness. The messy wirings in these systems make it
difficult to place anywhere.
To overcome the above limitations, we will use GSM Modem which would provide Wireless medium,
better reliability and ease of sharing information over a wireless media.
1.3. Project description:
It will require a specified user to send a message to the GSM modem connected to the
microcontroller in a pre-defined format. When a new message will be received by the GSM
Modem, Modem send the signal to Microcontroller. Then Microcontroller give command to
LED Matrix Board to display. The display can be taken as a NOTICE BOARD for a
school/College. The line driver circuit has been used to interface the GSM Modem with the
microcontroller to make their voltage levels compatible to each other.
