Materials:

Arduino nano

WS2812B NEOPIXEL LED

3D Printed Parts


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++

 }
