High everyone...

I am new here and am looking for a little help. I am trying to create or purchase an LED chaser circuit that chases 10 LEDs. I want have two of the LEDs on at once and have them chase in one direction. I would also like to control the speed of how fast they chase.

I should also tell you that each of the 10 "channels" will have 3 white LEDs and I want to run it on 12v.

Like I said, I could built my own, but does anyone know of a place where I could purchase a pre made PCB? If not, I have no problem making my own.

Thanks in advance,
Greg

Maybe use two 4017 chips with one being a step ahead of the other and have diodes on the output going to a couple driver chips like the ULN2003A Very Happy
