Salve,
ho collegato Arduino Uno R3 e Ethernet Shield R3 insieme,collegato con USB e cavo RJ45 al MacBook e il codice come prova è questo (vedi qui sotto) in altro modo come posso?Io uso Arduino 1.0.1 per programmare,ma alla fine mi dice errore della libreria w5100.cpp e w5100.h.Che cosa devo fare?Grazie.

Code:

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


byte mac[] = {  0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };
char serverName[] = "www.google.com";

EthernetClient client;

void setup() {
  Serial.begin(9600);
   while (!Serial) {
    ;
  }


 
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    while(true);
  }
  delay(1000);
  Serial.println("connecting...");

 
 
  if (client.connect(serverName, 80)) {
    Serial.println("connected");
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();
  }
  else {
    Serial.println("connection failed");
  }
}

void loop()
{
  if (client.available()) {
    char c = client.read();
    Serial.print(c);
  }

  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();

    while(true);
  }
}

Ciao,
su WinXP, IDE 1.0.1 compila perfettamente.

Prova a riscaricare l'IDE e ricopia qui sul forum gli errori che ti da. Cosi ci facciamo un'idea più precisa.

Va bene, scaricherò gli errori che mi dà,grazie PaoloP.

Ho appena provato con macbook, UNO, ETH shield tutto R3 e compila senza problemi

Salve,
ho collegato Arduino Uno R3 e Ethernet Shield R3 insieme,collegato con USB e cavo RJ45 (no cavo cross over-incrociato) al MacBook e il codice come prova è questo (vedi qui sotto).Al Monitor Seriale compare così:
coconnecting…
connection failed

disconnecting.
Che cosa devo fare?Grazie.

Code:

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


byte mac[] = { 0x90, 0xA2, 0xDA, 0x0D, 0x23, 0x1F };
byte ip[] = {  192,168,2,4 };
byte server[] = { 173, 194, 35, 151 }; // Google
byte subnet[] = { 255, 255, 255, 0 };    //subnet mask of the network
byte gateway[] = { 192, 168, 2, 1 };   //your router's IP address

EthernetClient client;

void resetEthernet() {
  client.stop();
  delay(1000);
  Ethernet.begin(mac, ip, gateway, subnet);
  delay(1000);
}
void setup()
{
  Ethernet.begin(mac, ip);
  Serial.begin(9600);

  delay(1000);

  Serial.println("connecting...");

  if (client.connect(server, 80)) {
    Serial.println("connected");
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();
  } else {
    Serial.println("connection failed");
  }
}

void loop()
{
  if (client.available()) {
    char c = client.read();
    Serial.print(c);
  }

  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
    for(;;)
      ;
  }
}
