## Article

#### **Bylnk Ethernet 예제**

```plaintext
#define BLYNK_PRINT Serial

#include <SPI.h>
#include <Ethernet2.h>
#include <BlynkSimpleEthernet2.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "YourAuthToken";


void setup()
{
  // Debug console
  Serial.begin(9600);

  Blynk.begin(auth);
  // You can also specify server:
  //Blynk.begin(auth, "blynk-cloud.com", 80);
  //Blynk.begin(auth, IPAddress(192,168,1,100), 8080);
  // For more options, see Boards_Ethernet/Arduino_Ethernet_Manual example
}

void loop()
{
  Blynk.run();
}
```
