Schematic & Wiring Diagram

Digital hours to create this not too tough.

This clock only displays hours and minutes, to seconds but you'll install the led associated with a series of I Hz oscillator formed from IC 555 (which I do, because I do not recognize the program listing).

a pair of led in parallel and installed as a bookmark seconds. Led to two installed in the middle of the hours and minutes. though with the approach that seconds and minutes if observed (calculated) decline slightly however i am not the problem, Moreover individuals won't understand it.
