I’ve read the wiki and it only says that the output pin is gpio 3, I ve connect the output pin with the di on the light, but it doesn’t work. Are there anything wrong with the other connection ?
How many LEDs do you want to drive from the ESP itself? Because it can make around 7-800mA which might be too low amperage for the WS2812 so it doesn't turn on. The ESP itself only can drive around 10 LEDs safely, but it might need a level shifter.
Also are you sure that the used LED strip is WS28xx? Some others looks the same but not supported. More info here
Also the two most important thing:
I try to make it work like this. As you just said, I think there is not enough power supply. There seems to have a 3v pin and a vin pin on the nodemcu, what should I do to make it have enough power supply.
!
So if I only cut a small pieces of the led strip, can it work with the power supply of a usb.
I've flash the firmware and successfully added accessories to HomeKit. But I have some questions about how to connect my nodemcu (esp8266 12f) and ws2812b.
I'm not sure which io connects to which port on the ws2812b. Should I connect gnd-gnd, vin-5v? and which pin should connect to Di to control the light. Can you tell me how to connect all these things when using this firmware? thank you very much.
