Hey,
I think you are misunderstanding me.
Its ONLY to count a 'ten' UP.
Not down.
But,
To count the 'hundred' up and down.
Along with everything else.
If that is alright??
Thanks

Hey,
Update to the circuit:
- The Tens Work (Thanks), But Do Not Update The Next Numbers, eg, 10,20,30...80,90,00 (<-- should be 100),10...
- The Original PTMs that count up and down in stages of one count all the digits updated: 0000,0111,0222,0333,0444,0555 etc
- Also, sorry about this part, but if it is possible, i need it to count down in the hundreds too, along with the count up. Thanks
Thanks for all your help. I would be grateful if you know a solution to the above problems.
Thanks

Hey,
The Tens/Hundreds count up still, but not down.
I am also still stuck with the problem of the units.
It counts like 0000,0111,0222,0333 etc.
What would you suggest to solve this problem??
Also, you mentioned that it would be easier to program the PIC to count up. How would you say i could do this. If it is much easier, then why not have a go for it??
Thanks for all your help!!

Hey,
My problems, unfortunately, continue to persist.
Firstly, the units count up and down now, but the tens do not change automatically (0000,0001,0002,0003...0008,0009,0000)
Secondly, both switches to count up and down for both the tens and hundreds to do work at all.
Those are the problems i can currently identify.
Attached is my circuit diagram.
Thanks

PS. I am from London. I do not see how this is relevant to the circuit??
Hey,
I am not sure when you will reply but thanks for all your help so far.
Attached is my circuit, which i have tried to copy as exactly as possible.
Your have to look at the displays right to left.
My only problems are that the tens and hundreds are not counting at all.
Thanks a lot

Hey all.
I am trying to make a circuit using the 4029 and 4511 that counts up and down.
So far it counts up and down in stages of one.
How would i make it count up and down in stages of 10 and 100 along with 1?
In other words, i want to do the following...
0000,0001,0002...0008,0009,0010,0011 etc
0000,0010,0020...0080,0090,0100,0110 etc
0000,0100,0200...0800,0900,1000,1100 etc
Thanks a lot in advance

[The attachment below is my circuit so far, that already counts in stages of 1]
Hey,
I know this must be getting annoying and so i apoogise for that.
I have connected up the circuit with the 4 pin AND and OR gates.
All the switches count up/down only in the units decade.
How can i prevent this?
Thanks

[Sorry again for the constant bother]
hi,Hey,
Yes, that is exactly what i wish to have
