DIGITAL CLOCK
At this time most peoples in the whole world use an automated digital clock in their everyday use. Starting from the hand watch we were to those huge street clocks every one of us are dependent on the display the make. In 21th century time being more than money, regarding this change our hobbies of checking our time every minute is dramatically increasing. About 99% of today’s digital clocks are made using microcontrollers which make them more hand able from the rest, those we can set the time to start any minute or second we want and also set an alarm for reminder so that the system will store the value in a memory and then when the time reaches the alarm will be on. As the microcontroller consists almost all the logical devices external logic gates doesn’t exist.
In order to be used properly and for a long life usage digital clocks must cover a very small place as much as it could but the size of most of the digital clocks manufactured this time is unexpectedly increasing as the use the give increases. This are the list of problems that exists in today’s digital clocks
An extensive range of large.
Use of independent LED matrix digital wall for the display that takes a huge space in the circuit and a lot of matrix code in the controller.
Displays only hour and minute. This makes the use they give us limited on the range given.
Not easy to maintain. When the clock gets damaged some can’t tell where the problem is easily, on the microcontroller or on the other driver ICS.
Very costly.
The system that is anticipated to be built consists of a 6 digit clock including hour, minute and second using a very cheap devices that covers a very favorable place. The design consists of all the features that a digital clock should consist and as the design is synchronous the overall delay is negligible.
