Well if i connect the PIN to DO Not the DI then it almost works. I think the color is reversed or something RGB -\> GBR?! And the last one is not doing what the other are doing.

```
#include "application.h"
#include "neopixel/neopixel.h"

SYSTEM_MODE(AUTOMATIC);

// IMPORTANT: Set pixel COUNT, PIN and TYPE
#define PIXEL_PIN D2
#define PIXEL_COUNT 3
#define PIXEL_TYPE WS2812

Adafruit_NeoPixel strip = Adafruit_NeoPixel(PIXEL_COUNT, PIXEL_PIN, PIXEL_TYPE);

void setup()
{
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}
void loop()
{
    strip.setPixelColor(0, 255, 0, 0);
    strip.setPixelColor(1, 255, 0, 0);
    strip.setPixelColor(2, 255, 0, 0);

    strip.show();
    delay(250);
    strip.setPixelColor(0, 0, 0, 255);
    strip.setPixelColor(1, 0, 0, 255);
    strip.setPixelColor(2, 0, 0, 255);

    strip.show();
    delay(250);
}
```
