The proposed method consists of electronic notice board that is controlled by an android device and displays message on it. Traditionally, there were notice boards where any information or notice had to be stick daily. This becomes tedious and requires daily maintenance. The project the overcomes this problem by introducing an electronic display notice board interfaced to an android device through Bluetooth connectivity. The Bluetooth receives the message from the android device that is sent to an Arduino. Notice board is a primary thing in any institution/organization or public utility places like bus stations, railway stations and parks. But sticking various notices day-to-day is a difficult process. The Notice board is a common display for effective mode of providing information to the people, but this is not easy for updating the messages instantly. This project deals about an advanced Hi-Tech wireless Notice Board. This system is enhanced to display the latest information through an Android application of smart phones or tablet.
In this proposed method, the development of a simple and low-cost wireless Android based notice board is presented. The proposed system uses either Bluetooth or Wi-Fi based wireless serial data communication in displaying messages on a remote digital notice board.
Android based Application programs available for Bluetooth and Wi-Fi communication for personal digital assistant (PDA) devices are used for transmitting the alpha-numeric text messages. Using the Bluetooth or Wi-Fi based serial data communication technique, the corresponding transceiver module has been interfaced with microcontroller board at the receiver end. For this purpose, a low-cost microcontroller board (Arduino Uno) is programmed to receive alphanumeric text messages in any of the above selected communication modes. The proposed system will help in reducing the human effort, paper, printer ink and cost for manual changing of the notices.
The development of cellular networks in the 1970’s for increasing the lack of frequencies in the radiotelephone services which in turn lead to introduction of AMPS (Advanced Mobile Phone System) where the transmission was analog based. This was known to be the first generation in cellular networks . The second generation was based on digital transmission and was called with various abbreviations as GSM (Global System for Mobile communications), ERMES (European Radio Messaging System).
Various Cordless telephone standards were also introduced during this time only. The third generation has risen with the unification of different technologies; some of them which are popularly known are FPLMTS (Future Public Land Mobile Telecommunications System), UMTS (Universal Mobile Telecommunication System), and IMT-2000 (International Mobile communication). These days, BLUETOOTH technology has become one the most popular medium for wireless data transfer. It has a wide range and is efficient in its work

When information exchange occurs between people via a network, then authentication and security of data have more priority. This paper introduces a low cost, handheld, wireless electronic notice board by using Atmel’s ATmega32 microcontroller and different wireless technologies (Bluetooth and ZigBee) and their performance analysis based on the parameter such as range, BER (bit error rate), RSSI (Received signal strength indicator), signal attenuation and power consumption. The notice board receives serial data from wireless module receiver and displays it on the graphical liquid crystal display. We have realizeda common communication receiver hardware for notice board having compatibility with both wireless modules i.e., Bluetooth and ZigBee. We used KS0108 based 128x64 graphical LCD as display element.

In the day-to-day life, smart phone is gaining a wide range of importance in its usage and is portable. Thus, an android smart phone can be for the purpose. An android application is installed in the user’s smart phone which permits the transmission. At receiver end, a low-cost microcontroller board (Arduino Uno) is programmed to receive and display messages in any of the above communication mode. Using the developed system, two different applications for displaying messages on a remote digital notice board and wireless person calling has been implemented. The developed system will therefore aim in wirelessly sharing the information with intended users and also helps in saving the time and the cost for paper and printing hardware.
III. PROPOSED METHODOLOGY
The proposed method consists of power supply, Arduino UNO, LED module, Bluetooth HC-05 and mobile application. After uploading the program in Arduino UNO, we will give them external power supply. Due to that all functions of equipment’s are on. At that time, we will pass the notice/SMS which we want using mobile. Then this notice/SMS will receive by Bluetooth. And by using Arduino this notice/SMS will display on digital notice board.
This proposed system in this project has many upcoming applications in educational institutions and organizations , crime prevention, traffic management, railways, advertisements etc. Been user friendly, long range and faster means of conveying information are major bolsters for this application. By using this proposed methodology, we can enhance the security system and also make awareness of the emergency situations and avoid many dangers.
IV. HARDWARE IMPLEMENTATION
A. Arduino uno
Arduino board is the heart of our system. Entire functioning of system depends on this board. The Arduino Uno is a ATmega328p microcontroller board. This board has 14 digital input/output pins (6 as a PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
B. Bluetooth HC05
Bluetooth Terminal is an Android application program that enables the Android PDAs to communicate simply with a Bluetooth device via a terminal. Bluetooth Terminal application program therefore enables the Android PDA to transmit (or receive ) the messages in either hexadecal (hex) or string format to (and from ) the connected Bluetooth devices. At the receiver end, the HC-05 module is interfaced with microcontroller that is programmed to store the received message and display that to the LCD screen. The HC-05 is a very cool module which can add two- way (full-duplex) wireless functionality. The Bluetooth module is used for transmitting data wirelessly from the transmitter to receiver. The HC-05 module works on the same principle but on the different operation. The HC-05 Bluetooth module has four pins: TX pin – Transmitting pin which is used to transmit the data. RX pin – the pin that receives data from the receiver. VCC pin – power supply pin. GND pin – power supply pin.
We utilize screen as display. LCD is utilized in a project to visualize the output of application. Liquid crystal displays (LCDs) have supplies which combine the properties of both liquids and crystals. With the liquid crystal material sand witched in between them, an LCD consists of two glass panels. The inner surface of the glass plates are covered with transparent electrodes that identify the character, symbols or patterns to be displayed and the polymeric layers are present in between the electrodes and the liquid crystal, which makes the liquid crystal molecules for maintaining a defined direction angle.
D. Bread Board
A breadboard (sometimes called plugblock) is used for building temporary circuits. It is useful to designers because it allows components to be removed and replaced easily. It is useful to the person who wants to build a circuit to demonstrate its action, then to reuse the components in another circuit.
E. Jumper Wire:
A jump wire is an electrical wire, or group of them in a cable, with a connector or pin at Stranded 22AWG jump wires with solid tips. Individual jump wires are fitted by inserting their "end connectors" into the slots provided in a breadboard
