In many public places such as colleges, railway stations, bus stands and shopping centres, display boards are used to provide information to people. Traditional display boards require manual updating, which can take time and effort. To overcome this problem, a Wireless Text Scrolling Display System is developed. This project uses an Arduino UNO, HC-05 Bluetooth module and LED matrix display to create a wireless communication system. A mobile phone with a Bluetooth Terminal application is used to send text messages. The HC-05 module receives the message and sends it to the Arduino through serial communication. The Arduino processes the message and displays it on the LED matrix in scrolling form. The system allows users to update display messages easily without physical connection to the display board. This project provides a low-cost, simple and efficient solution for wireless information display in various public and commercial places.
