Hi,
I had an LED strip laying around from a project last Christmas and decided to mod one of my wife's decorations. Last year when I did this I wanted the strip to go crazy rainbow-y which worked great. This time I would like things to be more controlled. As an initial test I drove one LED on the strip at a time. This is where I see my first issue, All LEDs that are off actually have a tiny little blue light coming out. Enough it messes with my other all idea. I haven't found a way to turn off the LEDs completely? (One workaround is to put the LEDs on a digital out pin so I can turn the whole pin off and all the LEDs. That doesn't help with I just want a couple on.) Next I started experimenting with randomly bursting some LEDs. The requested LEDs light up but I also see the surrounding pins going off and commonly in different colors. Is this normal for these LED strips? Are there any tricks to avoid this issue?

Thanks!
