Wireless Notice Board Using Bluetooth and Arduino

Abstract

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.

Introduction

I. INTRODUCTION

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
