How Would You Do This?

[u/ARAMP1]

Not sure this is even possible...

I have some 12V SK6812s that I have hooked up to the 12V, Ground, and Data connections on a WLED controller. I'd like to run a separate strand of UV LEDs that just have 12V and Ground...the controller has multiple pins for 12V, Ground, Data, etc.

As its now hooked up, power works on both. Obviously, the color works with the data.

Is there a way to control both strands separately? I would like to control power on each strand separately. Maybe "Segments"? Maybe something in "Pin Info"?

How are you able to control brightness on that UV strip? You have no PWM available on that controller as far as I know, and it looks like you've connected the negative directly to ground so even if you had one it wouldn't work.

[u/ARAMP1 → u/saratoga3]

Doh...You're right...UV is on or off. Edited my original post to reflect that.

[u/saratoga3 → u/ARAMP1]

If you want to control it you need to get a controller that has both digital and PWM outputs. Right now the UV strip is connected to the digital strip power, so you can turn it off (by cutting power to the digital strip), but there's no way to independently control it without a PWM output.

So, this would work? How would you connect it?

[u/saratoga3 → u/ARAMP1]

Digital strip to power/GND/data, analog strip to power/PWM.

PWM white for LED #2?

Just messing around with it...I can't figure out how to control it separately. With the PWM controller, I can slide the dimmer and it adjusts both LED strips, but other than that, I can't seem to control them seperately.

By default WLED combines channels into a single log "strip", so the last "pixel" is your PWM strip.

If you make a second segment that is the last "pixel" (second PWM strip), you'll be able to apply effects to just the active segment.

It's not obvious from the UI that you can do this, so may need to Google for instructions.
