CRGB leds[NUM_LEDS];
void setup() {
  FastLED.addLeds<WS2812, LED_PIN, GRB>(leds, NUM_LEDS);
}
void loop() {
  leds[0] = CRGB::Red;  // Set the LED to red
  FastLED.show();
  delay(1000);
leds[0] = CRGB::Green;  // Set the LED to green
  FastLED.show();
  delay(1000);
leds[0] = CRGB::Blue;  // Set the LED to blue
  FastLED.show();
  delay(1000);
}

# Set up the WS2812 LED on GPIO 18 (change as needed)
pixel_pin = board.D18
num_pixels = 1
pixels = neopixel.NeoPixel(pixel_pin, num_pixels, brightness=0.5, auto_write=False)
while True:
    for i in range(255):
        pixels[0] = (i, 0, 0)  # Fade in red
        pixels.show()
        time.sleep(0.01)
for i in range(255, 0, -1):
        pixels[0] = (i, 0, 0)  # Fade out red
        pixels.show()
        time.sleep(0.01)
```
Note: These examples are meant to demonstrate the basic usage of the WS2812 LED. You may need to adjust the code to fit your specific project requirements.
