Hello, I'm new to the forum so please bear with us 
I have libreelec installed on RPI3 B +. Now I dreamed of ambilight there. I bought WS2812B diodes and wanted to connect and configure it somehow. Unfortunately, I don't think I can do it myself, so I'm asking you for help.
Which GPIO in RPI should be connected with the data pin ?? I downloaded the hypercon.jar program and put something up there, I even wanted to send it to RPI, but it probably didn't work out.
Will someone help what to do, or maybe there is some current step-by-step instruction on how to start it ??
