Construction Of An Adjustable Electronic Flasher
This project (Construction of an adjustable electronic flasher) was constructed using available materials. Flashing circuits are very interesting. They grab your attention and can be used in many applications. They consume very little energy and a single cell can last as long as 12 months. You can flash globes, LEDs and pulse all types of devices such as motors, solenoids and piezo diaphragms. In this discussion we will cover a number of interesting “oscillator circuits.” They can be adapted for other applications – but to do this you have to know how they work. This is not easy as most of them are quite complex. In fact oscillator circuits are one of the most difficult circuits to understand. But if you read the text, everything will become clear. Flasher circuits have developed over a long period of time, with many of the earlier designs proving to be unreliable. The main aim of this work is to build an adjustable LED flasher circuit.

CHAPTER ONE
1.0 INTRODUCTION
Flashing circuits are very interesting. They grab your attention and can be used in many applications. They consume very little energy and a single cell can last as long as 12 months. You can flash globes, LEDs and pulse all types of devices such as motors, solenoids and piezo diaphragms. In this discussion we will cover a number of interesting “oscillator circuits.” They can be adapted for other applications – but to do this you have to know how they work. This is not easy as most of them are quite complex. In fact oscillator circuits are one of the most difficult circuits to understand. But if you read the text, everything will become clear. Flasher circuits have developed over a long period of time, with many of the earlier designs proving to be unreliable.
- OBJECTIVE OF THE STUDY
The objective of this research work is to construct an adjustable led flasher. The project is aimed to have couple of advantages over a flashing LED that can be buy as an individual item. The project is also the objective of the researcher to design the project with the most economical and efficiency parts so as to make it affordable to everyone.
- PURPOSE OF THE STUDY
The main purpose of this work is to build an electronics flashing circuit with a variable level of illumination.
- SCOPE OF THE STUDY
The scope of the operation of the adjustable electronic flasher fully automated. It pulses it with a higher peak current to give a brighter illumination and consumes less average current. This means it will work for a long time on an almost flat battery and cost nothing to run. It is built with the 555 timer IC that is powered from 2 x 1.5V batteries. The circuit can be used as a flashing metronome, dark room timer, memo-reminder or other similar applications
- SIGNIFICANCE OF THE STUDY
It can be used for battery equipment to indicate the power is ON or as an ALARM ON indicator. You can use a super-bright LED and get a really bright flash, or an ordinary green, orange or yellow LED to get something better than a flashing red LED.
1.5 LIMITATION OF THE STUDY
The following are the problem encountered during the research work.
- TIME: The research of adjustable electronic flasher is a time consuming exercise for collection, analysis and preparation of its report Goods research takes time to plan and executed.
2. COST: It is very costly to plan and implement this assertion in view of the fact that make research require the use of human resources, other resources and considerable time for the execution.
3. EXACTNESS: To ensure the behaviour of human being, it is impossible to predict such behaviour with absolute exactness or accuracy.
1.6 PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this work is on the introduction to this study. In this chapter, the background, significance, purpose, scope, objective, limitation and problem of this work was discussed.
Chapter two is on literature review of the study. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
The Title Page should be the first section of your project “Construction Of An Adjustable Electronic Flasher”, providing essential details like the project title, your name, your supervisor’s name, the institution, and the submission date. After that, the Abstract offers a brief summary of your project, touching on its purpose, methods, results, and conclusions in 150-300 words. The Acknowledgments section is where you can thank those who supported your research, such as your supervisor, peers, or organizations that provided resources.
Next, the Table of Contents organizes the Construction Of An Adjustable Electronic Flasher by listing its chapters and sections, along with page numbers for easy reference. The List of Figures and List of Tables help guide readers to specific visual elements like graphs, charts, or tables included in the document. There should also be an Abbreviations and Glossary section to explain any specialized terms or acronyms, making the content clearer to readers unfamiliar with the technical language.
The main body of the Construction Of An Adjustable Electronic Flasher should start with the Introduction, which provides background information, outlines the research problem, states your objectives, and gives a brief overview of your research methods. Following that, the Literature Review offers an in-depth look at previous research relevant to your project, identifying gaps your study aims to address. The Methodology section then explains the research design, tools, and data collection methods you used to conduct the project and analyze the data.
In the Results and Discussion section, you present your findings and discuss them in relation to the Construction Of An Adjustable Electronic Flasher research questions or objectives, often using tables or charts to help explain the data. The Conclusion summarizes the key results, discusses their implications, and suggests possible directions for future research. You may also include recommendations based on your findings, offering practical advice for improvements or applications. Finally, the Construction Of An Adjustable Electronic Flasher project should include a References or Bibliography section to list all the sources you cited, as well as Appendices for any additional material. A Statement of Originality is often included to confirm the authenticity of your work
