Display/Scoreboard Using LED Dot Matrix

Abstract

Digital display advertisement or scoreboard is the current requirement of the modern business and information world. LED Matrix Display is one of digital displays that displays programmed information. The use of electronic advertising displays is widely used as it is a more creative technology for displaying information on the go and engaging graphic design. This project was created to solve some of the problems that arose with existing usage, including displaying the same display all the time. This project is not only to display advertising but more for general use, as it can be used as a stopwatch and scoreboard for both indoor and outdoor sports or games. Researchers used Bluetooth application software programmed into an Arduino microcontroller. It is being carried out by using Bluetooth Applications to send information to led displays. MIT App Inventor software was used to produce android applications. Besides that, the DS3231RTC also used to transmit time to LED displays. It provides the facility of real time matrix displaying, which means the user can change the message that is to be displayed. The aims of the project are to develop a wireless portable message board that facilitates the user to switch the message content without having to connect the board to a cable and design a phone application that controls the display. The use of Bluetooth makes it easier to customize text in dot matrix views such as time, date, and scoreboard.
