hello all!
i need to do a little project on multisim that combine those components:
74LS48D and 74LS160D and some resistors.
well, i have started my project but i reach a point that i dont know what to do. im attaching my file so you can see what i did until now.
i need to build second, minutes and hours clock with 7-sigment.
as you see in my file i did only the seconds, its only count until 9 sec.
how to make it count to 60 sec?????
and how to make the minutes and hours properly?
thank you very much!!
:)

ok i know that, but how you make him count until 60 sec? after that 1 min should be appeared on the next 7-segment screen.

A few external gates can give an output at the count of 60 and even reset the counters to 1 at the next clock pulse by using the parallel load function. The same pulse can combine with the clock to count the next section (seconds -> minutes, or minutes -> hours).
