Pinout

Pin Description
VCC Power supply, connect to +5V
GND Ground, connect to Arduino GND
DIN Data Input, connect to Arduino digital output pin
DOUT Data Output, use for cascading to next module

Arduino Wiring

  • VCC → 5V on Arduino
  • GND → GND on Arduino
  • DIN → Digital Pin 6 on Arduino (example)
  • DOUT → Connect to DIN of the next module if cascading

Library

Download and install the FastLED library from: http://fastled.io/

Arduino Example Code

#include <FastLED.h>
#define NUM_LEDS 64
#define DATA_PIN 6
CRGB leds[NUM_LEDS];
void setup() {
 FastLED.addLeds<WS2812, DATA_PIN, GRB>(leds, NUM_LEDS);
 FastLED.clear();
 FastLED.show();
}
void loop() {
 // Simple rainbow effect
 for(int i = 0; i < NUM_LEDS; i++) {
 leds[i] = CHSV((i*5 + millis()/10) % 255, 255, 255);
 }
 FastLED.show();
 delay(20);
