CHAPTER ONE
1.1 INTRODUCTION
Communication has become inevitable and vital thing in this present age, it is even believed to be a commodity meant for consumption by any targeted audience. One of the important qualities possessed by all animals is the ability to communicate with each other or one another at a given time.
An information display is a way of providing information and is used as an object for notification. It can be used for both indoor and outdoor which makes it universal fit for any form of alerts.
The extent of development in information dissemination has made it possible that the well known method of displaying information using sign posts, placards, notice boards, etc has to be modified by using electronic information board.
In the previous years, the means by which adverts, information are display has been through the use of static mode of sign display such as banners, flyers etc, they are becoming boring and unattractive.
Electronic scrolling message display advertisements are designated to catch a people’s attention and create a memorable impression very quickly, leaving the reader thinking about the advertisement after they have driven past it. They have to be readable in a very short time because, they are usually read while being passed at high speeds.
This piece of digital technology can be found in a number of places and are being used for different purposes.
In banks, it is used to display interest rates as well as exchange rates. In hotels and pubs, it is used to display the menu and prices, in schools it is used to display information related to the school programme and update news
1.2 MOTIVATION
The motivation of this project comes from the change involved with information in respect to time this days now prompt the huge step of constructing a reprogrammable SCROLLING MESSAGED DISPLAYER OR MOVING MESSAGE DISPLAYER to give information about anything at a particular moment to the targeted audience and need to know how electronic billboards can at least provide some improved measures to the limitations of conventional billboards listed in the problem statements. The astonishing and spectacular display of an electronic display is as well a source of inspiration.
1.3 AIM OF THE PROJECT.
To design and construct an outdoor-scrolling message display
1.4 OBJECTIVES OF THE PROJECT WORK
- To design and construct an electronic display board with back-up battery which can be used to pass across information such as emergence phone contacts in form of scrolling message to staff, students and general public within the school premises.
- To know the various electronic components that makes up an electronic billboard.
- To design and construct an electronic message displayer with backup battery that will serves as a link of communication within the school premises
- To have practical knowledge on how these electronic components are interface and controlled to achieve the desired results.
- To develop and implement how a microcontroller can be interface with a LED dot matrix display board
- To have a good knowledge and understanding of the software/firmware needed to control the hardware section.
- To acquire more knowledge about digital world.
