// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

IPAddress ip(192, 168, 1, 177);

unsigned int localPort = 8888;      // local port to listen on

// An EthernetUDP instance to let us send and receive packets over UDP

EthernetUDP Udp;

  Udp.begin(localPort);
