The initial design criteria for the project were: to have a two digit output, to have the circuit count from 0-99, to include either a 555 timer or manual counter. Research was conducted into similar analogue electronic circuits and a suitable point of a digital die was identified. The digital counter circuit was designed using BCD 4506 binary counters and 7-segment display outputs. The circuit was modeled using proteus, which showed that the concept used in the design was okay. The circuit was then implemented and tested on a bread board before transferring it to a mother board. There are two modes of operation of the circuit: through manual switch which increments on its push, and through a 555 clock which increments automatically. In the end we were able to design and construct a two-digit, digital counter that was able to count between 0-99 using a 4026IC, shadow sensor and a 555 timer. The input clock pulses were from shadow sensors. We also discovered that the counter could be used to count many real world events; in different sectors.<\/div>\n<div><\/div>\n<div>TABLE OF CONTENT<\/div>\n<div>Title page i<\/div>\n<div>Certification ii<\/div>\n<div>Dedication iii<\/div>\n<div>Acknowledgement iv<\/div>\n<div>Abstract v<\/div>\n<div>Table of content vi<\/div>\n<div>List of tables ix<\/div>\n<div>List of figures x<\/div>\n<div><\/div>\n<div>CHAPTER ONE<\/div>\n<div>\u00a0Introduction \u00a0 \u00a0 \u00a0 \u00a01<\/div>\n<div>1.1 Types of circuit 2<\/div>\n<div>1.2 Purpose of design 4<\/div>\n<div>1.3 Scope of the study \u00a0 5<\/div>\n<div><\/div>\n<div>CHAPTER TWO<\/div>\n<div>\u00a0 \u00a0 \u00a0 Literature Review 6<\/div>\n<div>2.1 Electron counters 6<\/div>\n<div>2.1.1 Asynchronous (RIPPLE) Counter 8<\/div>\n<div>2.1.2 Synchronous Counter 11<\/div>\n<div>2.1.3 Decade counter 13<\/div>\n<div>2.1.4 Ring Counter 14<\/div>\n<div>2.1.5 Johnson Counter 16<\/div>\n<div>2.2 Computer Science Counters 17<\/div>\n<div>2.3 Web counter 18<\/div>\n<div>2.4 Computer based counters 19<\/div>\n<div>2.5 Mechanical Counters 19<\/div>\n<div>2.6 Microcontrollers \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 21<\/div>\n<div><\/div>\n<div>CHAPTER THREE<\/div>\n<div>\u00a0Design and construction of a two digit digital counter \u00a0 \u00a0 \u00a024<\/div>\n<div>3.1 Design Work 24<\/div>\n<div>3.1.1 Circuit Description 35<\/div>\n<div>3.1.2 Software Design 36<\/div>\n<div>3.2 Working Principle 39<\/div>\n<div>3.3 Working of the Circuit \u00a0 \u00a0 41<\/div>\n<div>3.3 The Construction Work 42<\/div>\n<div><\/div>\n<div>CHAPTER FOUR<\/div>\n<div>\u00a0Tests and Application 45<\/div>\n<div>4.1 Test \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a045<\/div>\n<div>4.2 Applications 46<\/div>\n<div><\/div>\n<div>CHAPTER FIVE<\/div>\n<div>\u00a0Discussion, Suggestion For Further Research<\/div>\n<div>And Conclusion 49<\/div>\n<div>5.1 Discussion 49<\/div>\n<div>5.2 Suggestions for Further Research 51<\/div>\n<div>5.3 Conclusion 52<\/div>\n<div>\u00a0REFERENCES 54<\/div>\n<div><\/div>\n<p>For complete work and download of this work and more, <a href=\"https:\/\/afribary.com\/read\/5297\/design-and-construction-of-a-two-digit-digital-counter-1475\" target=\"_blank\">Kindly click here to log onto our Website and download it.<\/a><\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>ABSTRACT In this work, we designed and constructed a digital counter circuit.
