Arduino

For programming the Arduino, we will use the FastLED library.

This is an excellent and well documented library which enables easy control of the WS2812B LEDs.

Sample Code

#include <FastLED.h>
#define LED_PIN     7
#define NUM_LEDS    20

CRGB leds[NUM_LEDS];

void setup() {

  FastLED.addLeds<WS2812, LED_PIN, GRB>(leds, NUM_LEDS);
}

void loop() {
  leds[0] = CRGB(255, 0, 0);
  FastLED.show();
  delay(500);
  leds[1] = CRGB(0, 255, 0);
  FastLED.show();
  delay(500);
  leds[2] = CRGB(0, 0, 255);
  FastLED.show();
  delay(500);
  leds[5] = CRGB(150, 0, 255);
  FastLED.show();
  delay(500);
  leds[9] = CRGB(255, 200, 20);
  FastLED.show();
  delay(500);
  leds[14] = CRGB(85, 60, 180);
  FastLED.show();
  delay(500);
  leds[19] = CRGB(50, 255, 20);
  FastLED.show();
  delay(500);
