Network-Based Digital Notice Board

In this project, we propose advanced hi-tech wireless notice board. Notice board is a primary thing in any institutions, organization, hospital, or public utility places. For passing any notice, we use papers. If we observe, lots of papers are being wasted due to this notices so we need to save papers in order to make an eco-friendly system. We are trying to develop a digital notice board which can overcome these problems. With this notice board, we can send our notice anytime without wasting any resource and can make our communication more efficient. We can handle proposed notice board with less errors and maintenance. We can replace normal notice board with digital notice board anywhere like institutions, organization, hospital, or public utility places and can update the notice anytime. For this, we used Raspberry Pi for wireless communication. Here we can change the news or notice or timetable which can be displayed on notice board. Raspberry Pi will act as server, and there will be multiple clients connected to the server, and these clients are connected with LCD. Here server and clients are connected via router for wireless communication. For displaying information, we need to approach server and from server, we can send our information to particular client or multiple clients and clients will be displaying that particular information. The goal of this paper is to provide the access to notices and articles quickly as compared to manual notice board. We can update text messages using centralized database anytime. The address is assigned to each receiver and information is displayed from the main server at the reception.
