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 digitalised 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:
1. Demonstrate the principle of scanning
in television system as applied to an electronic notice board.
2. Demonstrate the principle of
multiplexing in data communication as applied to an electronic notice
board.
3. Demonstrate the coding system of a
bitmap image used in graphic work as applied to an electronic notice
board.
4. Description of a computer system
embedded on a single chip.
5. Features and limitations of such a
computer system on a single chip.
6. Covers the assembly language understood
by the microcontrollers.
7. Application of software compilers to
microcontrollers.
8. Interfacing microcontroller with infra
red remote control.
9. Effecting/controlling hardware with
software and software with hardware-interfacing.
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.
