Number of LEDs in the ring

Chaining

You can chain multiple rings by connecting the DOUT pin of one ring to the DIN pin of the next. All LEDs share the same data line and are addressed sequentially.

Arduino code example

#include <Adafruit_NeoPixel.h>

#define RING_PIN 2
#define NUM_PIXELS 16

Adafruit_NeoPixel ring(NUM_PIXELS, RING_PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  ring.begin();
  for (int i = 0; i < NUM_PIXELS; i++) {
    ring.setPixelColor(i, ring.Color(0, 150, 0)); // Green
  }
  ring.show();
}

void loop() {
  delay(10);
}
