### Artnet Receiver + FastLED
``` C++
#include <Artnet.h>
// declarations for Ethernet/WiFi
ArtnetReceiver artnet;
// FastLED
#define NUM_LEDS 1
CRGB leds[NUM_LEDS];
const uint8_t PIN_LED_DATA = 3;
void setup()

// setup Ethernet/WiFi...
// setup FastLED
FastLED.addLeds<NEOPIXEL, PIN_LED>(&leds, NUM_LEDS);
artnet.begin();
artnet.subscribe(universe, [](uint8_t* data, uint16_t size)
{
// artnet data size per packet is 512 max
// so there is max 170 pixel per packet (per universe)
for (size_t pixel = 0; pixel < NUM_LEDS; ++pixel)
{
size_t idx = pixel * 3;
leds[pixel].r = data[idx + 0];
leds[pixel].g = data[idx + 1];
leds[pixel].b = data[idx + 2];
}
FastLED.show();
});
}
void loop()
{
artnet.parse(); // check if artnet packet has come and execute callback
}
