That's the way it works, each output stays high until the next clock signal.
There is a work around. What are the outputs connected to?

All outputs are connected to separate diodes. These diodes are connected to an LED.

 

How do you know what the count is if all outputs connect to one LED?
So you want that LED to stay on for only a short time before the next clock signal?

Yes, that's exactly what I want. I want the led to flash every time I press the button.

 

Is there a simple way to prevent the output from staying high all the time?

Not clear what you mean. One output of the 4017 is always high. When do you want the LED to turn off?

 

How long of a flash?

 

Yes, that's exactly what I want. I want the led to flash every time I press the button.

So connect the LED to the button, not the 4017.

 

How long of a flash?

This is not very important. Actually, I won't be controlling an LED, the outputs will be connected to the signal pin of a relay. I didn't say this to avoid confusion. It is enough for the relay to detect the signal every time I press it.

 

So connect the LED to the button, not the 4017.

I can't do this. because the signal should be cut off when the button is pressed 8 times. and when another button is pressed it must start over.

 

When you get to the eighth button press should the LED stay lit and not flash?

I actually fixed this. But let me tell you anyway: it doesn't matter in either case. The only problem for me is that when I press the button the relay does not have time to turn off and on. Because it switches from high to high every time and remains in the open position all the time.

 

I cannot imagine any use of a relay where it does not matter how long it is activated.

I guess you're a little nervous? If active time was important I would know it. You can only answer if you know the answer to my question. Let me help you think a little bit though. Since the output of the relay is connected to 555, it does not matter how long the relay remains active. I can adjust this from 555.

Sorry, I didn't fully understand your question. I still haven't been able to solve the relay problem.

 

So the outputs from the 4017 are driving a relay which is connected to a 555.
Post this circuit please. Is a relay actually required is my thought.

If you using the signal trigger a 555, no relay is needed. And we would be giving you completely different advice if we knew that. Keeping back information can only get you worse answers.

And, the time of a pulse to a relay always matters. If you don’t believe me, try activating a relay with a 1 usec pulse.

I am beginning to feel like a dentist.

This is a project assignment and I was asked to use a relay. but I guess I decided to use the relay elsewhere. This challenges me. Even if the CD4017 is not connected to any battery, it detects this when I connect its output pin to 555. What kind of connection do I need to make to trigger directly with CD4017?

 

Somehow I managed to send signal directly from cd4017 to 555. But I still need the time difference between passes. For example, when I connect a single LED to q1 and q3 (via a diode), I can get two signals. However, when I connect it to q1 and q2, I can only receive a signal from q1. When I switch to q2 it doesn't detect it as a different signal. Because I change from high to high. Does anyone have any ideas to solve this problem? I tried to solve it with a capacitor but I failed. Maybe you know a solution.

 

I am using CD4017 and 555 IC. Every time I press the next button, a signal is sent to the 555 by the CD4017 and the LED turns on for a while (theoretically). But there is a problem. Since I go from high to high without dead time when I press the button, the 555 does not perceive this as a different signal. That's why the 555's trigger remains active all the time. Is there any way to solve this? And do you see any problematic connections or redundant connections in the circuit?
