ABSRACT - [ Total Page(s): 1 ]ABSTRACT This project is aimed at explaining the Design and construction of a digital wall clock with calendar. It give report on how we can achieve this aim and the primary objective of this work is to bring a vibrant digital clock display to everyone located within the vicinity where the clock is being installed, and the importance of clock is to tell time and date, so you can meet up with events and assignments, these are just few importance of CLOCK. In developing countries, time is a very important element of life, maximizing it will give you a better achievement. We shall discuss o

CHAPTER ONE - [ Total Page(s): 3 ]ï¶ Counting unit;Each unit of the clock is linked to a general purpose register for counting purposes. There is a routine program that handles counting up for each of the clock units (refer to appendix for codes of routine program). The time taken for each increase is determined in the routine handling it. The output of each counter is binary and therefore needs to be converted to seven segment display format. Another routine is program to handle this (refer to appendix for routine program).ï¶ Display decoder;The display decoder is a program that converts binary coded decim ... Continue Reading
CHAPTER TWO - [ Total Page(s): 6 ]CHAPTER TWO3.0 LITERATURE REVIEWThis project is an embedded system that uses a microcontroller to achieve the required functions. This device operates by running a software program burn into its flash memory, this is divided into loops, and each loop has it specific function. These loops are labeled counter, decoder and display scanner.In this project, I have built a digital clock with 24 hour count time. The clock runs from 00:00 to 23:59 and then back to 00:00. The display has two four digits, two digits for minutes and two for hours. Six displays for the date and year. The special ... Continue Reading
CHAPTER THREE - [ Total Page(s): 6 ]ROM is used to permanently save the program being currently executed. This is why it is often called a ‘program memory’. The PIC16F877 has 8Kb of ROM (8192 locations in total). Since ROM is made with FLASH technology, its contents can be easily changed by providing a special programming voltage (13V).No further explanations are required as the whole process is performed automatically by means of a special program installed on the PC and a simple electronic device called the programmer. ...

CHAPTER FOUR - [ Total Page(s): 3 ]CHAPTER FOUR4.0 THE CONSTRUCTION After proper design and calculations for each stage, the components were obtained and connected together on a breed board and tested to ensure that the circuit connections were okay before it was transferred to the vero-board and soldered. The construction of each unit was carried out stage by stage with proper testing after each completion. The construction started from the power supply unit to the visual display unit and the casing.During soldering, care was taken to avoid dry joint by ensuring that the soldering iron was hot enough and that the c ...

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 CONCLUSION This digital clock is designed to display real time clock and calendar. There were lots of problems encountered while working on this project. These include generating clock signal of 1sec from 4Mz clock signal of the MCU, Synchronizing the timing along with the scanning of the display simultaneously and writing code fired into the microcontroller. Other problems encountered include choice of components, obtaining and interpreting datasheet of components for proper biasing. These problems were solved after due consultation and gathering of information. ... Continue Reading
