Circuit:

Code arduino:

#include <FastLED.h>

 #define NUM_LEDS 20

 #define LED_PIN 2

 CRGB leds[NUM_LEDS];

 uint8_t startHue = 0;

 uint8_t deltaHue = 0;

 void setup() {

  FastLED.addLeds<WS2812B, LED_PIN, GRB>(leds, NUM_LEDS);

  FastLED.setBrightness(50);

  delay(2000);

 }

 void loop () {

  fill_rainbow (leds, NUM_LEDS, startHue, deltaHue);

  FastLED.show();

  delay(50);

  startHue++;

  deltaHue++

 }
