I have an esp32 and it should be connected to the ws2812b but the led Strip does not light up or show any sign of working (the esp is showing up on the Website)
Post some photos of your wiring setup.
How many LEDs?
How are you powering the LEDs and the ESP32?
What ESP32 are you using?
Have you got a levelshifter in place?
Did you set the correct gpio in LED Preferences?
Thanks for your help and for the replies
So i Figuren it out but still have a question. How do you power ws2812b with an external power supply but still being able to Control colors etc. ?
That was the Problem thanks
Power the LEDs with V+ and Ground from the power supply.
Power the ESP32 with it’s own power (or USB)
Connect the data from the ESP32 to the LEDs with ground and data.
Thanks for the help would have been lost with out it
