Aşağıdaki kod ile ardunio ide izleme ekranından sıcaklık verisi geliyor. Fakat IP'e bağlanmak istediğimde bağlanmıyor ve tarayıcıdan ip girmek isteyince ardunio ide'deki veri akışıda duruyor nedendir?

#include <SPI.h>
#include <Ethernet.h>

// The IP address will be dependent on your local network:

};

// Initialize the Ethernet server library
// with the IP address and port you want to use
