Abstract

This project proposes an Abstract Wireless Notice Board system designed to overcome the limitations of traditional notice boards, such as outdated information and delayed updates. The system utilizes an Arduino UNO microcontroller and an HC- 05 Bluetooth module for wireless communication, allowing users to send messages from a mobile device to the notice board. By using voice commands through a Bluetooth app, users can easily update or change the displayed notice, which is then shown on an LCD screen in real-time. This voice-controlled functionality enhances convenience and accessibility, making it easier for users to update the board without needing technical skills. The system is cost-effective, secure, and efficient, offering a modern solution for timely communication. It is particularly useful in educational institutions, where quick access to relevant information is essential. By ensuring that notices are updated instantly, this system reduces confusion and ensures that im
