CHAPTER

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
I.
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.
II.
To know the various
electronic components that makes up an electronic billboard.
III.
To design and construct
an electronic message displayer with backup battery that will serves as a link
of communication within the school premises
IV.
To have practical
knowledge on how these electronic components are interface and controlled to
achieve the desired results.
V.
To develop and
implement how a microcontroller can be interface with a LED dot matrix display
board
VI.
To have a good
knowledge and understanding of the software/firmware needed to control the
hardware section.
VII.
To acquire more
knowledge about digital world.
