Using a 74HC74N to create a the display for the hours in a 12 hour clock

[Captain_Gondor]

Hello all,

I have been working on implementing a digital clock in Multisim and am nearly complete. I am currently having trouble making the hundredths count from 0-9 and then 0-2 and then resetting after 2. For the hundredths place I am using a 74HC161N counter while for the tenths place I have decided to use a D flip flop (74HC74N) which I am having trouble implementing as well. I have attached the file that I am working with, any help would be great.

Hi,

Out of curiosity, this is not an issue you have with Multisim, but the implementation of flip flops correct? There is a lot of forums that are made to help you with this kind of stuff (Some physics, electronics, and cirucitry forums) if you search around the web.

Kind regards,
