[sdiy] Bi-Color LED Question

[Ken Elhardt]

Okay, thanks.  Yeah, I had a single pot for the center lead, which
takes a positive voltage, and then would hook up the two outer leads
to ground.  But it sounds like I should put the resistors on the two
outer leads to ground instead of one on the center lead.  I'll give it
a try.

As for Elby Designs who didn't respond to the list, it's a 3 lead LED.
 Since I'm ordering parts soon, I'll probably pick up one of those RGB
LEDs with 6 leads to try out.  I should be able to get any color out
of one of those.
