What about Counters?

[Bilal.a.d]

I tried many times to build a counter using Flip Flops but the main problem is that those flip flop does not read or act on raising and falling edges!!, so what is the solution

Hi,
I guess you need to build edge flip-flop first and then your counter should work just fine.
You can share your circuit here on the forum so we can try to identify the problem together or you can just grab some working one from the forum or sample circuit.
Thanks,
