REMOTE NOTICE BOARD USING GSM WITH SMS
INTRODUCTION
This project and implimentation is based on VTU syllabus. The proposed system is based on ATMEL 89S52 µcontroller which is in our syllabus.
For doing this project and implimentation we use some of the software like
 Embedded C for programming the application software to the microcontroller.
 Protel schematic software is used for designing the circuit diagram for this project and implimentation.
 Express PCB software is used for designing the PCB for this project and implimentation.
(Since PCB making is a big process and involves lot of machineries which are expensive, we are going to outsource this to the manufacturer.)

ABSTRACT :
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.
Suppose the same message if the person wants to display in main centers of the cities means he have to go there with laptop and change the message by connecting into PC.This project and implimentation we can use mainly for police or army .I.e. displays will be connected to all the main centers in city if they wants to display messages about something crucial within 5 minute, they can’t
So keeping in this mind 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 and implimentation is a remote notice board with MODEM connected to it, so if the user wants to display some messages, he will send the messages in SMS format the MODEM in the display system will receive the message and update the display according to the message. For every message received from the user mobile, the system will check for the password and if the password is correct the controller will display the message. the LED s on the digital display board uses the latest hi-bread LCD modules (hi-bright), where LEDs are mounted on a rectangle plastic like enclosure and then wired as the 8/5 led matrix with 5 column and 8 rows. These LED’s have more brightness compared to the other LED now available in the market.

COMPONENTS USED:
 Power Supply 5v DC - 7805
 Microcontroller - P89C51RD2 -Phillips
 Crystal - 11.0592 MHz
 Shift register - 74HCT164
 Memory - Atmel 64k EEPROM
 MAX 232 - For Serial Communication
 Buzzer - Freq-1 to 18khz.Volt-5v-12vDC
 GSM Transmitter and Receiver
 5*8 led matrix display

SOFTWARES USED:
 Embedded C.

WORKING PRINCIPLE:
This is a very good project and implimentation for college, police etc. This project and implimentation has a moving message display, which can be used as the digital notice board, and also a GSM modem, which is the latest technology used for communication between the mobile and the embedded devices.
System will work like when the user wants to display or update the notice board, he have to sent the message in his mobile defining the messages and then the password of the system to the number of the sim which is inserted in the display system MODEM. Then the MODEM connected to the display system will receive the SMS, the microcontroller inside the system is programmed in such a way that when the modem receives any message the microcontroller will read the message form serial port and verify for the password, if the pass word is correct then it will start displaying the messages in the display system
The messages are displayed on the system using high speed techniques, the entire display column is connected to shift register output so that the characters are first shifting to each column and then the microcontroller will switch on the row one by one with small delay. This process is continuing in high speed so that the viewer will feel the display in a more brightness

INTRODUCTION
1.1 General Introduction:

In today’s world it is said that, world is shrinking day by day. It is due to the fact that people from different parts of the world are able to communicate with each other within fractions of seconds. All these advantages are possible due to the advantages in digital communication techniques. With the advent of cellular technology the use of mobile telephones are increased drastically over the years. In today’s world of technological advancements communications and control is necessary in any part of the world.
The novel idea of this project and implimentation is to receive message through mobile phones and send it to Notice Board for display. This project and implimentation is basically a micro controller- based design used to control remote notice board. P89C52RD2BN is heart of this project and implimentation. Here, we use mobile phones as a message sender, sending messages to notice board by sending appropriate SMS and receiving SMS whenever there is no problem. The mobile used is GSM technology.
The key strength of GSM is its international roaming capability giving consumers a seamless service, superior speech quality, universal and in-expensive mobile phones, Digital convenience, New services(Call waiting , Call forwarding, SMS). SMS is a GSM service by which we can send and receive data, to and from another GSM handset. The message can be comprised of words or numbers or an alpha numerical combination.
The main advantage of SMS service are it’s an available communication tool those with speech or hearing difficulties. And if you get an SMS and you are outside of the GSM coverage area SMS will be stored and you will be received it as soon as you entered the network coverage area. This will always keep you aware of the security situation of your home/office.
Using “attention commands” (AT Commands) GSM modem operations can be controlled.
1.2 Objective of the study:
The main objective of selecting this project and implimentation is to gain knowledge and experience in developing a real time application. Apart from this, to gain the Knowledge of P89C52RD2BN Micro Controller, GSM modem and the way in which these can be used to receive messages and display on notice board.
8052 is a popular micro controller. There are number of 8052 applications. Micro controller can be programmed to run only one specific application.. It can be programmed to accomplish the specific job faster.
GSM modems are widely used in mobile phones. The working of the modem can be controlled by “AT” commands. There are many “AT” commands like “AT+CMGR” to read a message etc.
1.3 Scope of literature:
System using GSM includes only three applications. Notice Board are connected to the system just to show that, it is possible to control various notice board using micro controller.
In this project and implimentation the software has been written to send and receive messages. When a message has to be sent a command is sent to the GSM modem. But, this project and implimentation would not guarantee, that the message sent would reach the destination, if GSM service does not exist. This is not in the scope of this project and implimentation.
1.4 Review of the Project:
Many books have provided valuable information that was very useful for this project and implimentation.
One such book authored by MD. ALI MAZIDI and JANICE GILLIPSE MAZIDI titled “THE 8052 MICRO CONTROLLER AND EMBEDED SYSTEMS”.
1.5 Introduction to EMBEDED SYSTEMS:
Embedded systems are designed to do some specific task, rather than be a general-purpose computer for multiple tasks. Some also have real time performance constraints that must be met, for reason such as safety and usability; others may have low or no performance requirements, allowing the system hardware to be simplified to reduce costs.
An embedded system is not always a separate block - very often it is physically built-in to the device it is controlling. The software written for embedded systems is often called firmware, and is stored in read-only memory or flash convector chips rather than a disk drive. It often runs with limited computer hardware resources: small or no keyboard, screen, and little memory.
Wireless communication has become an important feature for commercial products and a popular research topic within the last ten years. There are now more mobile phone subscriptions than wired-line subscriptions. Lately, one area of commercial interest has been low-cost, low-power, and short-distance wireless communication used for \personal wireless networks." Technology advancements are providing smaller and more cost effective devices for integrating computational processing, wireless communication, and a host of other functionalities. These embedded communications devices will be integrated into applications ranging from homeland security to industry automation and monitoring. They will also enable custom tailored engineering solutions, creating a revolutionary way of disseminating and processing information. With new technologies and devices come new business activities, and the need for employees in these technological areas. Engineers who have knowledge of embedded systems and wireless communications will be in high demand. Unfortunately, there are few adorable environments available for development and classroom use, so students often do not learn about these technologies during hands-on lab exercises. The communication mediums were twisted pair, optical fiber, infrared, and generally wireless radio.
CHAPTER 2
DESIGN

The systems design process partitions the requirements to either hardware or software systems. It establishes the overall system architecture. Software design involves the representing the software system functions in a form that may be transformed into one or more executable programs. The design involves the design of hardware as well as software part required for the project and implimentation.

Description:
The AT89C52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 and 80C52 instruction set and pinout.The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C52 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
The AT89C52 provides the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full-duplex serial port, on-chip oscillator, and clock circuitry. In addition, the AT89C52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. The Power-down mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next hardware reset.
