CHAPTER ONE
INTRODUCTION
The world as it stands now can be said to be digitalised in every ramification and as such this project is aimed at looking for the way to change the way the time of the day is computed and displayed to the end user. In this method a microcontroller PIC16F877A is being used and this will calculated the time based on the number of the internal instruction is has executed and reflect the result in digitalized form on a series of matrix seven segment display.
Infra red signal will be the line of communication between the digital clock and the end user through which the digital clock’s time can be modify/set.
Operating basically on the mains power supply, a backup battery power supply will be inculcated to provide power supply to the entire power system in the absence of mains power supply.
AIM OF THE PROJECT
To design and construct microcontroller based digital clock for the real time dissemination.
OBJECTIVES
· To be able to calculate the time using microcontroller (16F877A)
· To be able to interface a microcontroller to sharp remote control
· To be able to display the date and time in a digitized form on a matrix 7 segment display
SCOPE OF STUDY
This project work is to cover the following area:
METHOD OF STUDY
The compilation of this project is as a result of research carried out using library for consultation of various textbooks, magazines and journals to source for useful information. Several internet websites were visited to get relevant information on the project topic. The amendment and testing of circuit as well as the construction of the whole project was done in the laboratory. The valuable and constructive guidelines, advices and instructions as provided by my project supervisor also helped achieved the set target.
