Design And Construction Of Digital Clock

Electrical Electronics Engineering | Industrial Physics | Physics

The design and construction of a digital clock involve the integration of electronic components and programming techniques to create a timekeeping device that displays the current time digitally. Key components include a microcontroller, such as Arduino or Raspberry Pi, to process timekeeping algorithms and control the display; a real-time clock (RTC) module for accurate timekeeping; LED or LCD displays to show the time digits; and additional components for power supply and interfacing. The construction process entails assembling the electronic components on a prototyping board or PCB, writing and uploading the necessary code to the microcontroller, and configuring the RTC module for accurate time tracking. By leveraging programming skills, electronic knowledge, and proper assembly techniques, a functional digital clock can be efficiently designed and constructed, offering precise timekeeping in various settings such as homes, offices, or public spaces.

ABSTRACT

Digital clock project is developed for the users to use a digital clock. The main parts of this project are set switch, microcontroller unit and LCD display.

This Project Digital clock using microcontroller is an advanced digital Clock, which displays the time using LCD or seven segment display. This device display time in seconds, minutes and hours. The system has an inverter which is used to power the system.

The user can set the time, date and day using the switch. When the user sets the timings, the settings will be displayed in the LCD display. When the function key is turned on, the controller sends pulse to the LCD display to display the current time.

INTRODUCTION

1.1 BACKGROUND OF THE PROJECT

Digital clock is very useful projects for final year students.. It has an Inbuilt Real Time Clock which tracks over the Real Time. It displays the time in hh:mms format. The time and date can be changed at any Time using the swtich. The Real Time Clock is displayed on LCD display.

A digital timing circuit (digital clock) is something we use and depend on every day. The timing circuit used in this project will be entirely hardware based. It will consist of two timing signals, a 60Hz clock pulse used as the main timing signal (multiples of 60s) and a 1kHz clock pulse used for multiplexing a 7-segment display for the clock. The 60Hz clock pulse will be divided by sixty multiple times in order to provide a pulse for seconds, minutes and hours. These pulses will be counted, stored in memory registers and then displayed to show the current time.

1.2 PROBLEM STATEMENT

The first clock that was invented was analogue clock which has no other features apart from time and it also consumes higher power and stops working as soon as the power battery is removed. These disadvantages also happen in our digital clocks – their time is reset or stopped as soon as the system power battery or source is removed. However, digital real time clock came to overcome these problems. Digital time clock counts hours, minutes, seconds, months, days and even years digitally.

1.3 OBJECTIVE OF THE PROJECT

The objective of this project is construct a device that will display the time in seconds, minutes and hours. In addition to this, it will also display time. We can also set the time using the switch.

1.4 SIGNIFICANCE OF THE PROJECT

You truly cannot be an organized human being unless you use a good timing system! And if you’re still someone who likes to keep all of their appointments, activities – I highly encourage you to consider tossing out the paper and find an electronic clock system that works for you.

One of the most beautiful things about digital clock is that they can be synced, so you can have your clock on your smart phone, your tablet, your laptop, as well as it can sync to your husband’s electronic clock and your kids’ clock. So no matter where you are- you can easily look up and see what your current appointments are for any given day. And the important people in your life can know the latest schedule and commitments too- without coming home and consulting the kitchen wall.

1.5 ADVANTAGES OF DIGITAL CLOCK

Even if there is power failure, this clock displays the right time using an inverter.
Simplicity of the system.
Accuracy of the system.

1.6 APPLICATIONS
Because digital clock is very small and inexpensive devices that enhance the popularity of product designs, they are often incorporated into all kinds of devices such as
• Cars
• Radios
• Televisions

1.7 METHODOLOGY

To achieve the aim and objectives of this work, the following are the steps involved:

Study of the previous work on the project so as to improve it efficiency.
Draw a block diagram.

Test for continuity of components and devices,

Design and calculation for the device was carried out.
Studying of various component used in circuit.
Construction of the circuit was carried out.

Finally, the whole device was cased and final test was carried out.

1.8 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 a digital clock. In this chapter, the background, significance, objective limitation and problem of a digital clock were discussed.

Chapter two is on literature review of a digital clock. 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.
