#include "Adafruit_NeoPixel.h"

#define LED_PIN   6
#define NUM_LEDS  12

Adafruit_NeoPixel ring(NUM_LEDS, LED_PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  ring.begin();
  ring.show();
}

void loop() {
  ring.fill(ring.Color(0, 0, 255)); // Blue
  ring.show();
  delay(500);

  ring.fill(ring.Color(255, 0, 0)); // Red
  ring.show();
  delay(500);
}
