DESIGN OF AN LED MATRIX DIGITAL DISPLAY SYSTEM
Main Article Content
Abstract
The digital display system is used for disseminating information to a crowd or a larger audience within a particular location. In today’s world of technological innovation, digital media is playing an important role in information dissemination as well as in the Educational sector in enhancing or keeping students abreast of academic work and the latest news around the campus. This paper is a detailed analysis of the design and implementation of a microcontroller-based digital display system, using wireless communication to send and receive information displayed on the display board. It has three sections; power, control and display. The designed system is made up of two parts, the hardware and the software. The hardware part is made up of many p10 modules (LED matrix), power supply modules, Esp32 microcontrollers, jumper cables and the aluminium casing. The software consists of the Microcontroller unit (MCU) code and the mobile application code. The MCU code controls the MCU functions, receives custom messages from mobile devices and displays them in a readable form by illuminating the corresponding LED. The mobile application provides an interface for the users to write and send custom messages to the MCU using WiFi communication.
