Hi,
I'm a new user here. I am juz a first year student who starts learning digital design.
As my project, I did a digital clock using 7490 IC. I use two 7490 decade counters to create divide-by-10 counter and divide-by-6 counter so that I could get a divide-by-60 counter. The counter has no problem and counting properly. But the problem lies in resetting the digits to 0 0. I cannot reset the counter and it starts counting from random digit. So how can I reset the counter?
After I got first Seconds Counter, I try to connect it with another divide-by-60 counter for Minutes counting. I connect the output of the first Seconds counter and the clock of the Minutes counter. I also find problem in resetting the time for the Minutes counter.
If anyone can help, I'm looking forward to your advice. =)
