i'm facing strange problems using the nodemcu (with the esp8266) and the led stip WS2812B: at the moment i'm trying to turn the led stip on by jsut connecting the red and white wires to the V- and V+ or this https://www.amazon.it/gp/product/B01LZF6NK6/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 (i have bought this one because the led stip wants DC5V and 0.60mA for each led, so more or less 18A)
I'm not wiring the green wire (the data one) because i just want to test the stip.
The result is that my led stip is not turning on. Is the stip faulty? do i have to connect the green wire too?
In order to connect the strip i have connected only the red and white wires (like thi https://www.info4blog.it/wp-content/uploads/2020/01/Schema_Striscia.png)
I also tried to connect the nodemcu to the power supply with the Vin and GN (using 5V) but without succes.
