        abstract = {This study details the design, development, and deployment of a wireless scrolling text notice board used an ESP32 microcontroller and a WS2812B LED strip arranged in a 60x7 matrix configuration. The system receives real-time messages via Bluetooth communication and presents them as animated scrolling text. It is powered by 5V 5A switched-mode power supply (SMPS), ensuring efficiency, stability, and reliability. The software development leverages the Arduino IDE in conjunction with widely used libraries such as Fast LED and Adafruit Neo Pixel, streamlining the programming process. This cost-effective and portable solution offers a modern, scalable alternative to conventional notice boards that necessitate manual updates. The paper elucidates the technical architecture, implementation, and potential applications of this system, establishing it as a practical and efficient tool for real-time information dissemination in educational institutions, workplaces, and public spaces.},
