Hi everyone,
I am having some problems trying to create a circuit for a 12 Hour digital clock circuit using 74LS90 IC's and 6x 7 segment displays to show the hours, minutes and seconds. I need the clock to have a start / stop and a reset function. Attached to this post is a screen shot of the circuit that I have so far, using the 7490 IC's.
Any help with this would be very much appreciated, as I am having real trouble in understanding how to make it work at the moment.
Thanks!
