Ethernet W5100 Shield For Arduino UNO Mega 2560 1280 328 UNO R3 W5100 Development Board

Ethernet W5100 Shield For Arduino UNO Mega 2560 1280 328 UNO R3 W5100 Development Board


New 2012 Version Ethernet W5100 Shield For Arduino UNO Mega 2560 1280 328 UNO R3 W5100 Development Board



For the Arduino Ethernet W5100 network expansion module, you can make the Arduino a simple Web server or Arduino digital and analog interface network applications through the network control read and write. IDE, Ethernet library files can be used directly to implement a simple Web server.

This Versions supports mini SD card (TF card) to read and write

The expansion board with a stackable design can be directly plugged into the Arduino our other expansion boards can also plug in to.
This Ethernet Shield which is based on the Wiznet W5100 Ethernet Chip. It gives you an easy way to get your Arduino Online. It is directly supported by Arduino official Ethernet Library. Built-in micro-SD card slot, which make this shiled supports SD functions that can be used to store files for serving over the network. It is compatible with the Arduino Duemilanove (168 or 328), Uno as well as Mega (1280/2560) and can be accessed using the SD library.
The Ethernet shiled 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.
You can run a test for the following 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 =;
// 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;
