Make a Digital Clock

I got an assignment to make a digital clock using Arduino Uno, Bread Board, IC's and other required things. I have no idea how to create a digital clock. Can anyone help me do this?

Start with a google search (800K hits) and/or search this site for "arduino digital clock".

If all you plan to ever do with an Arduino is make a clock,

Purchase an Arduino (an Uno would be my preference)
Purchase a bread board and jumper wires
Purchase an RTC (Real Time Clock)
Purchase an LCD screen

YouTube Arduino RTC. Lots of vids to get you started with making the wiring connections.
Write code to get RTC working properly.

Do the same for the LCD.
Then combine the two.

Way easier than all this sounds.

If you think you might want to try your hand at creating other things with an Arduino, I would suggest getting one of the many kits available all over the internet.
