ABSTRACT

This work is on “GSM Based Digital Display Bill Board” which can be used by institution, organization or any commercial establishment to display new event or activity to the public. It utilizes GSM, LED and microcontroller to display information.

Hence, this project aims at achieving the above purpose using GSM module which can feed the message dynamically. There is one particular advantage of using GSM Modem in this project. Since this involves SMS, the user can display message of choice even he/she is at any given place.

GSM Based Digital Display Bill Board is an automated microcontroller electronic system which scrolls text on an LED board, the message to be displayed can be dynamically changed using GSM module to which the user sends an SMS. The user also gets an acknowledgement in form of SMS on successfully displaying the text. In this project the first line of the message displays steadily while the second line of the messages moves and it is also editable.

When the user sends a text to be displayed via SMS, GSM module receives and transfers the text to microcontroller. The code in microcontroller converts each character in the text into a 2 Dimensional array of 1’s and 0’s. The array size depends on the size of the LED matrix being used on the LED display board. These 1’s and 0’s are fed to LED driver circuit, which does its own unique role. If the message is successfully displayed, the microcontroller sends a confirmation SMS to the user through GSM module.

In conclusion, this microcontroller based displaying of text on LED matrices board is advantageous, not to mention low cost, by providing dynamic yet simple and flexible aid to institutions, organizations or commercial establishments to display and scroll texts. The scope of application of this project can be expanded by the choice of the user. Our project is a modest prototype of integrating GSM Based Digital Display Bill Board

CHAPTER ONE

1.0 INTRODUCTION

1.1 BACKGROUND OF THE STUDY

Over the last few years, the GSM cellular phone has grown from a luxury item owned by the rich to something so common that one out of five people already owns one. This is amazing when we look at the fact that our country is a developing one with almost half our population living below the poverty line. This continuously growing popularity of the GSM cell phone has spurred the growth of the country’s cellular network infrastructure. The primary reason we can see for this tremendous and unexpected cellular boom is the popularity of the short message service (SMS). A variety of services have grown around SMS.

The GSM Based Digital Display Bill Board is aimed at the universities for displaying day-to-day information continuously or at regular intervals during the working hours. Being GSM-based system, it offers flexibility to display flash news or announcements faster than the programmable system (Umesh et al, 2013). GSM Based Digital Display Bill Board can also be used at other public places like schools, hospitals, railway stations, gardens etc. without affecting the surrounding environment. The led display system mainly consists of a GSM receiver and a display toolkit which can be programmed from an authorized mobile phone. It receives the SMS, validates the sending Mobile Identification Number (MIN) and displays the desired information after necessary code conversion. It can serve Mobile Identification Number (MIN) and displays the desired information after necessary code conversion It can serve as an electronic notice board and display the important notices instantaneously thus avoiding latency. Being wireless, the GSM Based Digital Display Bill Board is easy to expand and allows the user to add more display units at anytime and at any location in the campus depending on the requirement of the institute.

1.2 PROBLEM STATEMENT

Advertisements are made to pass information about a particular product or services to the public which is usually done via individual, newspaper, television, radio, internet etc. All this method of passing information are not 100% effective in that it can only benefit those seated watching, listening or reading the information – which is a problem. Also, traditional digital display only displays steady information which is also used to pass information to the public but the challenge with it is that the information cannot be edited. In order to solve this problem, a GSM Based Digital Display Bill Board was proposed. In this system displayed information can be changed or edited from time to time using GSM module. This work actually eliminate main problem involved in manually reprogramming the microcontroller which is responsible for displaying a new message or different style on the digital notice board. The challenge of reprogramming the microcontroller which is cumbersome, and cause endanger physical damage to the system, are therefore eliminated.

1.3 AIM AND OBJECTIVES OF THE PROJECT

AIM

The main aim of this project is to display a moving digital information which can be edited using GSM.  In this device, a text message is typed in the GSM mobile phone and sent it by using SMS service of the mobile phone to LED moving display boards. A GSM modem is connected to the LED display hardware is used to receive the SMS and send it to the controller circuit of the LED display. Then the controller circuit of the LED display filters the message content in SMS and changes the display text in LED display dynamically.

The objectives of this work are:

  1. To build a digital device (billboard) that can be used to display running text using GSM.
  2. To digitally pass information to the public.
  3. To display “HOD EET,” “STAY SAFE COVID 19”, “WELCOME TO ELECTRICAL ELECTRONIC ENGINEERING TECHNOLOGY”.
  4. To reduce the total cost that is required in the traditional LED display boards not only it makes easier to send message to the LED display boards.

1.4 SCOPE AND LIMITATION OF THE STUDY

The scope of this work covers designing a receiver (GSM MODEM) display board which can be programmed from an authorized mobile phone. The message that is desired to be displayed is sent through an SMS from an authorized transmitter (mobile phone). The microcontroller receives the SMS from the authorized transmitter, validates the sending Mobile Identification Number (MIN) and displays the desired information on an LED array which serves as the display board.  The main components used includes arduino microcontrollers, GSM MODEM, 7×96 characters LED display arranged in matrix configuration, max232 serial interface, electrically erasable programmable read-only memory (EEPROM), mobile phones, and voltage level conversion unit.

By using this this device (with SMS service) it is possible to change the text in the LED display board from anywhere in the country.

1.5 BENEFIT OF THE PROJECT

In all field of human endeavour, GSM Based Digital Display Bill Board plays very vital role, such as means of passing information, communication, presentations, exhibitions, identification and direction. It is also used in giving warning or safety instructions, such as warning signs, traffic signs, exit signs or signs conveying rules and regulations. This project write-up will be a guide to future designing in a related work.

1.6 SIGNIFICANCE OF THE STUDY

Working on this work as a student has exposed us on how GSM module can be interface microprocessor and LED. Also, it has made us to understand the need of passing information digitally.
