Yes, you can replace the chips with the arduino and do it all in software. Do some searching in the playground.

Hi. Im trying to make this digital clock...
Building that clock (and learning the function of each component) would be an excellent way to teach yourself the basics of digital logic.  I know that from personal experience since my EE was earned at the tail end of the vacuum tube era.  Why don't you just buy the parts via mail order?
