    I'm trying to build a simulated digital clock for my assignment using 4 7490 counters. My problem though is that I dnt know what to use to send the signal from the power supply to pin 14 on the counter. Also since I am generating my 1 Hz from my power supply what transformer can be used to attach to my AC power source when using the mULTIsIM simulator.

    I am using Ac power and a bridge rectifyer to convert it to DC and a 7805 Voltage regulator.

    I'm new at this so I need all the help I can get. :confused::confused::confused:

    Do you have a schematic of what you have so far?

    What I got from your post is that you are looking for the 60Hz signal from the power line for the clock?
