Hello, I don’t know if someone can help me, the case is that I have tried to connect in various ways and it is impossible for the WS2812b to work, I have fed 3 leds from usb, for 15 with power to the +5v pin from a power supply external and to gnd the negative of the source and I have tried a lot of GPIO, but nothing, I don’t know if this model is special
Not sure what this means:
Did you set the gpio in Led Preferences to the one you are trying to use and are you connected to the correct end of the LED strip? Data only flows one way.

Thank you very much, I did not know that the current flow was in one direction.
That was the problem, as I said, thank you very much
