A simple web server that shows the value of the analog input pins using an Arduino Ethernet shield.

Step 1: Prepare Your Arduino Kit and Ethernet Shield

Step 2: Plug Your Ethernet Shield to Your Board

#include <Ethernet.h>

// Enter a MAC address and IP address for your controller below.

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

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

IPAddress ip(192, 168, 56, 2);

// 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);

while (!Serial) { ; // wait for serial port to connect. Needed for native USB port only }

// 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();
