Digital Clock - an engineering project

As a part of course in Digital Logic we the students of BE in Computer Engineering studying at IOE, Pulchowk Campus were asked to build a digital clock. This is the first ever hardware project of my life. In this project we have used IC 4026 (and or IC 4033) as the counter. We've used 555 timer IC to generate 1 Hz signal and 7-segment display to display the time. The clock is provided with two push-buttons to change the time.
