Question

三天前我买了一个以太网屏蔽，但我的网络连接有问题。我无法访问屏蔽的IP地址。我知道Arduino和网络的基础知识，但我没有太多的以太网屏蔽经验。

我有Arduino UNO和Ethernet Shield W5100

以下是我正在使用的代码：

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

// 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);

// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);

void setup() {
  // Open serial communications and wait for port to open:
 Serial.begin(9600);


  pinMode(4, OUTPUT);
digitalWrite(4, HIGH);

  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip);
  server.begin();
   Serial.print("server is at ");
  Serial.println(Ethernet.localIP());
}


void loop() {
  // listen for incoming clients
  EthernetClient client = server.available();
  if (client) {
Serial.println("new client");
// an http request ends with a blank line
boolean currentLineIsBlank = true;
while (client.connected()) {
  if (client.available()) {
    char c = client.read();
    Serial.write(c);
    // if you've gotten to the end of the line (received a newline
    // character) and the line is blank, the http request has ended,
    // so you can send a reply
    if (c == '\n' && currentLineIsBlank) {
      // send a standard http response header
      client.println("HTTP/1.1 200 OK");
      client.println("Content-Type: text/html");
      client.println("Connection: close");  // the connection will be                       

      closed after completion of the response
      client.println("Refresh: 5");  // refresh the page automatically             

      every 5 sec
      client.println();
      client.println("<!DOCTYPE HTML>");
      client.println("<html>");
      // output the value of each analog input pin
      for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
        int sensorReading = analogRead(analogChannel);
        client.print("analog input ");
        client.print(analogChannel);
        client.print(" is ");
        client.print(sensorReading);
        client.println("<br />");
          }
          client.println("</html>");
          break;
        }
        if (c == '\n') {
      // you're starting a new line
      currentLineIsBlank = true;
        } else if (c != '\r') {
      // you've gotten a character on the current line
      currentLineIsBlank = false;
        }
      }
    }
    // give the web browser time to receive the data
    delay(1);
    // close the connection:
    client.stop();
    Serial.println("client disconnected");
      }
    }

这是错误：
