Abstract
This research presents a wireless noticeboard system using Arduino UNO, Bluetooth HC-05, and an LCD display to show messages. We have developed an Android application and an SQLite database for efficient communication and data storage. This system allows us to display messages and notices dynamically in environments such as colleges, schools, offices, and other public places. The Arduino UNO acts as the main controller, while the Bluetooth HC-05 module enables wireless communication between the Android application and the system. The Android application allows users to send messages to the noticeboard, with the data stored locally in an SQLite database which ensures efficient storage and retrieval of data, enhancing the performance and usability of the system. This solution offers a cost-effective, flexible, and scalable method for managing real-time information, significantly improving the traditional wired noticeboards by integrating modern wireless technologies and mobile app interfaces.
