Ethernet W5100 network expansion board SD expansion support MEGA development board
Product Description
The Arduino Ethernet W5100 network expansion module can make Arduino a
simple web server or network applications such as reading and writing Arduino's
digital and analog interfaces through the network control. A simple Web server can
be realized by directly using the Ethernet library file in the IDE.
At the same time, this version supports mini SD card (TF card) to read and write
The expansion board adopts a stackable design, which can be directly plugged
into the Arduino, and our other expansion boards can also be plugged in.
Experimental code in IDE:
/*
* Web Server
*
* A simple web server that shows the value of the analog input pins.
*/
#include
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 192, 168, 0, 15 };
Server server(80);
void setup()
{
Ethernet.begin(mac, ip);
server.begin();
}

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");
