Abstract
Digital display advertisements and noticeboards are essential in the modern, information-driven world. The hybrid message Light Emitting Diode (LED) display is a type of modern display system that presents programmed information and offers a creative solution for real-time information display and engaging graphic designs. This project extends beyond advertising, serving general purposes such as functioning as a real-time clock, date, and message display for both indoor and outdoor project seminars/presentations. The system utilized a Bluetooth mobile app that allows users to send messages to the LED display board wirelessly. Massachusetts Institute of Technology (MIT) App Inventor software was utilized to create the mobile app, and the DS3231 Real Time Clock (RTC) was used to send real-time data to the display. This setup provides a customizable real-time matrix display, enabling users to change the displayed message conveniently. A phone application was developed to control the display, creating a wireless, convenient message board that allows for easy content updates without physical connections. This solution addresses issues with existing systems that display static content. The wireless LED Dot Matrix display successfully operated with minimal errors and maintenance.
