Arduino
// Include Libraries
#include "FastLED.h"

// Define Global Variables
#define NUM_LEDS 300 // How many LEDs are in the strip
#define DATA_PIN 2 // Which pin on the Arduino?
int fadeAmount = 5; // How fast does it fade? e.g. Higher number = faster fade.
int brightness = 0;

// Define the LED Array
CRGB leds[NUM_LEDS];

void setup() { 
      // Based on which LEDs you're using. See FastLED docs.
      FastLED.addLeds<WS2812B, DATA_PIN, GRB>(leds, NUM_LEDS);
}

void loop() { 

  for(int i = 0; i < NUM_LEDS; i++ )
   {
   leds[i].setRGB(47,49,61);  // Set Color (RGB)
   leds[i].fadeLightBy(brightness);
  }
  FastLED.show();
  brightness = brightness + fadeAmount;

  if(brightness == 0 || brightness == 255)
  {
    if(brightness == 0){
      delay(20000);
    }
    fadeAmount = -fadeAmount ; 
  }    
  delay(10); 
    
}
