    Hi,

    Get the data sheet for a CD4017. Come back when you've decided what you want to use for a clock source, and what kind of LED's you want to use (voltage and current). You might want to look through Volume 4 of our E-book for some pointers on how logic works.

    A 4017 has 10 outputs, of which one is always on. Unless you gate the first LED to be off for the 1st or 11th count, then its not gonna do the trick.
    You really need a count to 11 circuit, not a count to 10.
