Hi all, i am new here, can i know what is the full programming codes to control WS2811 12V RGB LED Strip for running light 3 by 3 ?

No one mentioned this; but, since you're discussing WS2811.  That strip is 12VDC.  The Arduino's Digital Outputs are only +5VDC.  I'm thinking you would need to up convert the DIO's voltage to 12VDC, by using the 5VDC to drive an optocoupler, such as this:

No, the strip is powered by 12V but it's data line requires a 5V or 3.3V signal.

If you apply 12V to the data line, you may damage it.
