We need to create a circuit that repeats. You must keep time to 0.5 seconds for each part.
Only 0-1-2-3 is repeated and it is difficult to change after that.
It's not easy to use Tinkercad.
It's so hard to do on my own. Please help.

 

Is this homework?

 

Yes

 

School related homework is treated differently. We cannot do your homework for you. If you can show what you have accomplished so far then we can guide you.

A circuit schematic is the universal language used in electronics. Please post a circuit diagram.

This is an example of a circuit diagram.

You will notice that in the example circuit diagram posted in post #4, there are no crossed lines between the CD4511 and the 7-segment display.
(The one omission in that diagram is that the pin numbers on the 7-segment display should have been shown as well.)

It is your goal to show to the reader a circuit diagram that is most easy to follow with few crossed lines.
Signals generally flow from left to right.

 

If you look at the conditions for incrementing and resetting each digit of the three-digit number, it should be possible to assemble a combinational control circuit to achieve that by examining the binary value of each.

It would be helpful if you posted the complete instructions for the problem.

Your schematic is difficult to read. You have unnecessary wire crossings, scenic routes, too much whitespace, and the positioning of the AND gates makes it difficult to tell what they're doing. Print your schematics in black and white so they're easier to read.

 

시간ow to delete

You can't delete threads.

Are you able to use counter ICs?

 

Here's a redraw of your schematic:

Your schematic for reference:

I removed the erroneous connection circled in red.

 

Didn't have anything better to do, so I simulated your problem using commercial presettable counters and JK flip flops. I was surprised that the flip flops didn't need any gates for steering logic to implement the counters.

If the schematic you posted is supposed to be for the 0,1,2 counter and you planned to have it clock the 4,5,6 counter, you have things backwards. The 7,8,9 counter needs to change at the higher frequency.
