Design and Construction of a Digital Clock With Calendar

ABSTRACT

          This project is aimed at explaining the Design and construction of a digital wall clock with a 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 on how you can design one in this report with a well narrated literature review for better understandings. Also efforts were made in explaining the vital and important part of the design components and their functions in the project.
