    This product was added to our catalog on Saturday 01 November, 2014.

     This Ethernet Shield which is based on the Wiznet W5100 Ethernet Chip gives you an easy way to get your for Arduino Online. It is directly supported by for Arduino official Ethernet Library. It adds a micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the for Arduino Duemilanove (168 or 328), Uno as well as Mega (1280/2560) and can be accessed using the SD library.

    The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. Use the Ethernet library to write sketches which connect to the internet using the shield.

    Test Code:
    * Web Server
    * A simple web server that shows the value of the analog input pins.


    byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
    byte ip[] = { 192, 168, 0, 15 };

    Server server(80);

    void setup()
    Ethernet.begin(mac, ip);

    void loop()
    Client client = server.available();
    if (client) {
    // an http request ends with a blank line
    boolean current_line_is_blank = true;
    while (client.connected()) {
    if (client.available()) {
    char c = client.read();
    // if we've gotten to the end of the line (received a newline
    // character) and the line is blank, the http request has ended,
    // so we can send a reply
    if (c == 'n' && current_line_is_blank) {
    // send a standard http response header
    client.println("HTTP/1.1 200 OK");
    client.println("Content-Type: text/html");

    // output the value of each analog input pin
    client.print("welcome to tinyos");
    for (int i = 0; i < 6; i++) {
    client.print("analog input ");
    client.print(" is ");
    if (c == 'n') {
    // we're starting a new line
    current_line_is_blank = true;
    } else if (c != 'r') {
    // we've gotten a character on the current line
    current_line_is_blank = false;
