Paper Title
Smart Notice Board Using IoT

Abstract
Various establishments including bus stations, railway stations, colleges and shopping malls heavily depend on notice boards to facilitate communication between users. A manual update process with traditional analogy notice boards makes operations slow and inefficient. The project focuses on creating an IoT-based digital notice board through the integration between an ATmega328 microcontroller and a 16x32 dot-matrix LED display. The system allows users to conduct instant wireless message updates using a webbased interface. The ATmega328 microcontroller works at 16 MHz frequency to send messages precisely as well as show content for efficient communication. The system includes environmental temperature monitoring features which boost its operational capability. The use of IoT technology enables this wireless notice board to reduce manual work while delivering accessible paperless communication Keywords - Digital Notice Board, Iot, Atmega328, Dot-Matrix Display, Wireless Communication, Environmental Monitoring.
