DESIGN AND CONSTRUCTION OF A DIGITAL CLOCK
ABSTRACT
This project is a digital clock that uses logic circuit and binary operations in conjunction with LED seven segment display to display time digitally. This digital clock was designed for 24 hours time format and also digitally display seconds. The problem that is usually encountered using the analog display of time is that there is not much accuracy in the readings and the person using it has to calculate and interpret the hours and the minutes. The analog clock is displayed using a scale and a pointer, due to this, there is much parallax and human error in the readings which makes it has accurate. The solution to the problem outlined above is to design a digital clock which will eliminate parallax error and reduces human error and thereby giving a high level of accuracy in the readings. Another interesting thing about this digital clock is that it uses LED (Light Emitting Diode) type Seven Segment display and therefore can be seen in darkness which most of analog clock do not have. Though the cost of producing a digital clock is more that that of an analog type but the advantage of a digital clock is much more than that of an analog type. In consideration of the problems and solutions suggested, it is concluded that a digital clock is very useful and it will make life easier.
