Hi,
I would like to thank you all for helping me on my project, tomorrow is the deadline and I have had it printed and built on PCB and is working exactly as it is supposed to be.
Couldn't have done without the help from this wonderful forum! :-D
Cheers

Would it not work to have the switches as they are now? That way frequency can be paused at any moment rather than every 1 second, that's what I understand?
Sequence:
1 Second worth of frequency is input
The 4013 input is high
Reset Switch remains at 1 (closed)
Latch remains at 1 (closed)...
I've attached a function generator and set it to 2000 Hz directly into the input of 4013 to try and make it as simple as possible for the time being, at least for the simulation part. I will have to build it also a few days before my deadline due to no lab access... Hopefully will have enough...
Thanks for getting back to me on this wonderful Friday!
This is what happens when the frequency counter is connected, it displays (---) No frequency :???:
It's weird because no matter where I connect the frequency counter on the circuit, the frequency is non existent... At least that what the...
Ok, so I've had a look and decided to go with the 32.768Khz to 1Hz method, and have found a schematic online to follow to generate 1Hz, unfortunately, nothing works now and I'm not receiving any signal from the frequency counter when attached to the inputs.
I hope I've done everything right, as...
I understand what needs to be done, but I've run into another issue, I've been spending all day trying to figure out how to create this divider circuit. Multisim does not seem to have a 10Mhz crystal oscillator, so the next best thing from what I've researched is a 32.768KHz oscillator, but...
Hi again,
I have a switch now that connects the LE pins together, and when I open it, whatever is on the counter is frozen, and it does exactly what you said, it would update the counter if the LE switch is switched on and off even if the input switch is off...
I am struggling to understand...
Ok, I've succeeded in making a reset switch for all counters, and I've attempted to add the latches, and I've also wired up the frequency meter to the input gate to see what's happening, and as you said, the frequency changes very rapidly when the switch is opened and closed. Although the input...
Ok, I've cleared it up now, it counts fine with a clock input and I've included a switch so I can stop the counter counting up...
I can't figure out how to go from here...
I've finally managed to get the basic counter to work and have now made it so that it counts up and overflows to the next counter with the activation of a switch. now I just need to understand how to do with an automatic clock pulse which pauses and
A "Bit" of a mess, but definitely making...
I think I understand the theory behind the counter, after having a look at the JK flip flop and then using the 74LS90 to try and get a single output which in turn if I understand correctly, that the output of one would be the input to another 74LS90 for as many digits that were required, in my...
Hi,
I have been a set a project to complete by the end of the month, I do not know much about sequential logic circuits or any other aspects that are mentioned in the brief, so that leaves me in an awkward position as I do not know how to even begin. :-( The only things I have learnt so far is...
