THE DESIGN AND CONSTRUCTION OF A MICROCONTROLLER BASED DOT MATRIX ADVERT DISPLAY
INTRODUCTION
The purpose of this project is to produce a narrative description of the design and construction of a microcontroller based dot matrix advert display. Firstly computer aided design is the modeling of physical system on Computers allowing both interactive and automatic analysis of design variant and the expression of design in a form suitable for manufacturing. This follows by explaining the microcontroller based dot matrix advert display as a device which is fast gaining wide acceptance and application in the present days due to its ability to provide a very high precision timing. The dot matrix advert display can be describe as an electro-mechanical system for processing information in which the information is represented by physical quantities, which are so constrained to take only discrete values that can be referred to as binary signals.
In this design we have implored the use of both hardware and software to bring about the entire project. The hardware components are solely coordinated by the AT89S51 micro controller chip while the C- programming language is used to program the chip.
1.1 OBJECTIVE OF THE PROJECT DESIGN
Depending on ones intention, microcontroller based dot matrix advert display system have many aims and objectives.
For instance, this one in particular aims at displaying a moveable coded letters that says ‘UNIVERSITY CAFETERIA”
Also microcontroller based dot matrix advert display system can be used to control the traffic misunderstanding among motorists especially in junctions. This is achieved by displaying stop, get ready, or move. Some traffic control electronic system displays symbols or color that represents the stated commands above
Moreover, microcontroller based dot matrix advert display system is used in electronic scoreboard during football matches to display when a goal is scored, also to display the name of that player who scored the goal. Above all, this system has contributed a lot in boosting advertisement.
