Help with programming an LED knight-rider scanner!

Hippynerd:
Yes, i re-read my posts, I dont know why, but I re-read it for you.

I was wondering why anyone would put the resistor in parallel, because you said:

"Not if the resistors are in parallel - which they will be if they're "built in". "

I was replying to your post about resistors in series.

If the resistors are inside the LEDs they'll be in parallel (with each other), just like the LEDs.
