Need some advice about a Led switch

[catdady2k]

I want to use a switch to step through a ten LED string one LED at a
time. I also need to bypass a LED (take it out of the sequence) when I
want. I'm ginna be using a foot swtich if this matters. Any advice
will be greatly appreciated.

4017 decoded decade counter.

Now it's getting complicated. How do you plan to select which LED to
remove from the sequence?

and what happens when that led should have come on? no leds or the
next in the sequence? What happens when you reach ten and then over
step to the next - back to one?

Learn to program a PIC, AVR, ARm etc..

Add a buffer on the IO outputs and you can do as you please.
