Hi Everybody! Smile

Say "end" is the 16-step sequencer.
I put a switch were to occur it becomes 8 steps, that is, to use the first 8.

"Innocently" put the leg 13 of the first 4017 to land ground had to 8.

But ... actually having any armed, I see up to 8 does not count if it has up to 9.

That is, the LED 8 is off, there is a "step ghost" and then back to 1.

I noticed that for this purpose, I had to connect the leg 9 of the first leg 15 to 4017, but in doing so, the "ghost step" but will account 2-8 (not ignite LED 1)

Les image below as I have armed

I reiterate: HELP !!!!!!!!!!!!!!

Thank you

For those who still remember this topic: the switch is shorting out pin 9 Q8.
And I think it is better to use the reset pin for only 8 steps, ie using the nineth step as a signal.
