LED Strip Help

Hi there,

I would like some help in programming this LED strip I have and connecting it to the Arduino. It was purchased from ALDI Australia a while ago and has the four following connections:

  • +12v
  • GND
  • GND
  • DIN

All I can find online have the ports "12V" (or Vin, doesn't matter), "R," "G," and "B."

How should I approach this?
Also, I would love some sample code.

As it is 12V and one data in it looks like you have a WS2811 strip. Drive these just like the WS2812b strips, but in the software only say it has a third of the number of LEDs because on this type each controller chip actually drives three LEDs with the same colour.
