Design and Implementation of A Led Dot Matrix Display

Abstract

Information passage and sharing is very vital in the world of communication. In recent years there have been a call to modernize the information  passage processes and going by the human aesthetics taste for colorful and beautiful things and environments, there is a need, therefore, to introduce  aesthetics into the way information are displayed on billboard especially in a dark environment which characterizes Sub-Saharan Africa. In this paper,  therefore, the design and implementation of moving message display based on microcontroller was carried out. The display units which comprise  transformers, ATMEGA microcontroller, Filtration unit, uses Light Emitting Diodes LED in a 7 × 60 arrangement to form the predetermined characters, which lights up progressively as an effect. Once the message is completely displayed, it latches for a proposed time and abruptly disappears and the  process is repeated over again with the scrolling of characters.
