How to get a One-Wire address of a given WS2812B pixel? I bought several of these, and I cannot make them light. On the other hand, when I connect the addressable LED strip made of these diodes, I have no problem controlling it.
Here is my set-up:
I tried many programs, e.g. AdaFruit_NeoPixel -> simple, setting number of LEDS to 1, but no effect. No blinks, nothing - as if the diodes were dead.
If every One-Wire device is identifiable by 64 bit ID, how does the Arduino know the correct "order" of the LEDS on the ribbon? How to tell the Arduino the new sequence of the LEDS on the strip that would result if I replace one (broken) LED with another?
