Design and Development of a Smart Wireless Electronic Notice Board System

Abstract

For a long time, paper-based notice boards have been widely used in the government and private organizations, school areas to share information among the customer. However, using traditional (paper-based) techniques is a wastage of paper and paper-ink and human power. As a result, it is a time-consuming method and also it is not cost-effective. Therefore, to mitigate the aforementioned drawback, in this paper the design and development of a smart wireless electronic notice board are presented. The system is designed using a GSM module, Bluetooth module, ardiuno microcontroller, LCD, Buzzer, and LED. The circuit diagram and its functionality has been validated using the Proteus simulator. Based on the distance, the user of the proposed system can select one of the two approaches, are GSM modem-based and Bluetooth module-based approaches. The simulation and the hardware implementation of the proposed system are successfully achieved. From the result it has been realized that the proposed system is only accessed by authenticated users, it isa cost-effective system and very easy to handle. Besides, the latency involved in using papers in displaying notices is avoided. Therefore, the proposed system has many upcoming applications, as it can be set up at educational institutions and organizations, public transport places like railways, bus stations, airports, at the roadside for traffic control, and advertisements purpose
