All,
I have two separate strips of WS2811 LEDs. Both are 3 LEDs/IC and are 60 LEDs/m. Using the following diagram I am able to successfully illuminate and execute code via my FastLED library.
However, when I attempt to connect strip #2 independently of strip #1(which works) using the same configuration nothing happens. It doesn't even light up to all white. If I eliminate the arduino and run +12V from the battery directly to the LED strip and then use my Data wire as a ground it will light up 3 LEDs in Blue. Any ideas what is going on?
Update as of 8/13/2016
I apologize for not being clear in the initial post. I have included a photo of the two WS2811 strips. In addition a new diagram.
I wanted to make sure the lights in fact illuminate and turn on as they should so I attempted to connect the LED strip directly to the battery source. In diagram #1 using strip #1 all LEDs illuminate to 'Bright White' which is what I anticipated.
In diagram #1 using strip #2 I get nothing at all, all LEDs stay off. I figured the strand of LEDs was no good so I used the setup from diagram #2 for strip #2 and get 3 LEDs to illuminate to Blue.
Now looking at the photo of the actual LED strips you can see strip #2 has DI to DI connection. Maybe this was a manufacturing problem and there's just a defect with the strip?
