Hi guys. I gt a question about this MOD-6 Counter. (110)
Basically, what I could do now is to get the number to change from 0..1..2..3..4..5..0..1..2..3..4..5 . But then, I'm trying to make it look cooler by making it change from 0..1..2..3..4..5..4..3..2..1..0 . It seems that I gt a lot of error when making an attempt to make it like this. I have been trying this for the past few days. Any kind soul willing to help me? :)

With regards,
Lewis.

You can create a mod-6 counter with three flip-flops. To do what you are suggesting will require four flip-flops.

The 3 chips will be the one setting it to be a MOD-6 counter(110). So meaning the other chip I'll use it to make it count up and down?

While that is correct, I would look at it differently. The fourth flip-flop will be used to identify the count down sequence as new states.
0-1-2-3-4-5-C-B-A-9-0.

Remember, what you are building is a state machine. Use Karnaugh maps for this.
