CHAPTER ONE
1.1 Introduction
1.1 Background of Study
The Microcontroller Based Password Door Lock System is a design that applies automated security system in homes, Industries, military etc. The project will feature a system that will track the presence of an intruder in restricted area and also inform the user about the position of the intruder.
This Project will be based on microcontroller and other electronic design to achieve the above stated purposes. The interfacing medium will make use of parallel port. The sensors (Light Dependent Resistor and LEDS) will receive the signal when the intruder is around wile the control program will translate the received signal from the sensors to useful information about the function of the system.
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 AT89S52 micro controller chip while the assembly programming language is used to program the chip.
Therefore, in Nigeria where the research was carried out, the activities that was conducted is to Design and Construct a Microcontroller Based Password Door Lock System.

The depth of my work on this project will build a system that will be able to check the security of home and small industries. It will feature four (4) sensing circuits that could be check the intrusion of an intruder in up to four different positions or location. Single alarm system that will alert about the presence of an intruder and also, the display of an intruder position using the Visual Display Unit of the microcomputer.
1.5 Limitations of the Study
During the course of this study, many things militated against its completion, some of which are:
- Time Constraint: The time frame given to accomplish this project was very short due to school academic calendar and it was carried out under pressure which made the researcher not to implement some necessary features.
- Research material: availability of research material is a major setback to the scope of the study.
- Frequent power failure: This made the researcher append more money on fuel to ensure sustainable power.
- Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet).
