Design and Construction of a Double-Sided-Double-Line LED Matrix Display

Bello N. & Obasohan O.

Abstract

This paper describes a hardware and software design of a double-sided display of a dynamic message (alphanumeric characters) in a light-emitting diode (LED) matrix, from conception, design, dimensioning to realization. The development ensured the possibility of changing the scrolling text, adjusting the brightness, speed of the scrolling and setting the time and date displayed and projected as sound from an Android application. This study explores the design of scrolling dot matrix display systems using PIC18F2620 microcontroller, ULN2803 driver and shift registers. The brilliant design allows dynamism of displayed text on two sides controlled through Bluetooth from the Android application developed with Xamarin Studio which is all basic, quick and financially savvy therefore providing a solution to the laid-back paper-based notification system.
