CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND OF THE PROJECT
In the past, many systems that are designed by man are normally operated manually. This mode of operation is accompanied with many defects or disadvantages. Some of the disadvantages involve stress undergone by the operator; the operator is also exposed to health hazards when carrying out his or her duties. These health hazards might be in terms of electrocution, skin burn or bruises.
To overcome the above mentioned disadvantages that are associated with manual operation of systems, the recent systems are designed with mechanisms that enable them to carry out the required operations automatically. To this effect, the system carries out the required operation by them. The mechanism of the system can only be altered during servicing of the machine. With automatic operation of systems, the stress involved with handling the systems are reduced drastically.
The automatic gate control system is one of the systems that operate automatically. The system simply detects the presence of object at the front of the gate and then, opens the doors of the gate automatically. It incorporates sensors that are mounted at strategic positions and which has the capability of detecting objects. These systems are used in public offices where people often make use of the doors.
1.2 AIMS AND OBJECTIVE OF THE PROJECT
The main aim of the design is to practically obtain a system that opens and closes a given gate automatically, when there is presence of cars or persons. The system is designed in such a way that it has sensors that senses the presence of people.
1.3 SCOPE OF THE PROJECT
The design and implementation of microcontroller based automatic gate controller utilizes the characteristic operation of both passive and active electronic components such as resistors, capacitors and integrated circuits. The circuit is designed in a prototype forms and it is only meant for indoor demonstration of how the system works. The system also uses a programmable integrated circuit in its control unit. Meanwhile, this project, microcontroller based automatic gate control has sub units such as: Power supply unit The control section
The gate drive section The sensor unit

ABSRACT - [ Total Page(s): 1 ]Microcontroller based automate controller is a project design of a system that is used in operating a gate automatically. The system opens the gate automatically when a human being or car is about to enter a compound or exit a compound. The system works by sensing the light rays from the head lamp of the vehicle. The light ray is sensed and signal is used in operating the gate. Different blocks of circuit are put together to ensure that the system works perfectly as desired. The blocks include; ...
