1.1 Introduction
In most digital circuits there are only two voltage levels for example 0v and 5v. These voltages are referred to as logic levels. This logic is referred to as either 0s or 1s. Therefore grouping zero (0s) and one (1s) can monitor digital operation and information. This monitored information can be modified and stored. These two state circuits (0s and 1s) can be used to perform a wide range of control functions from single to complex digital electronics. The efficiency of the circuits is limited by the fact that it is software driven.
The heart of the electronics display is the micro controller. It is the part where logical operations are carried out. This micro controller contains a single integrated circuit. They are used to interpret the input, communicate with other devices and output data to a Variety of devices.
In this capacity, they can reduce the cost of products significantly by reducing the number of components required to carry out complex functions in the design of this project and also constitute a great deal of flexibility in the cost effectiveness and gives designers the choice of using the same hardware design for a variety of application with each unique software. The single fact is that, they can be used in such diverse applications indicates its versatility in taking over many tasks that were primarily considered beyond implementation.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitation of the study and Definition of technical terms.
