Abstract: Digital notice board systems have emerged as an efficient alternative to traditional paper-based information dissemination methods. By enabling real-time message updates, such systems improve communication efficiency in educational institution, offices and public spaces. This project presents the design and implementation of a Raspberry Pi based Android application controlled digital display notice board that allows wireless transmission of notices using Bluetooth communication. The proposed system integrates an Android application with voice-to-text functionality, enabling users to input messages through speech, which are then converted into text and transmitted to the Raspberry Pi. Despite the advantages of digital notice boards, challenges such as reliable wireless communication, real-time data processing, system scalability and secure access control must be addressed. Bluetooth-based communication, while cost-effective and suitable for offline operation, is limited by range and device pairing constraints. Additionally, handling dynamic message updates and ensuring smooth system performance require efficient software design and robust hardware integration. The Raspberry Pi zero 2W saves as the central processing unit, leveraging Python-based scripts to manage incoming data and display operations through an HDMI-connects screen. Despite these challenges, addressing them through improved modelling techniques, automated data collection, and interdisciplinary collaboration can significantly enhance the effectiveness of software testing and support more informed decision-making.
