ARDUINO W5100 Ethernet Network Expansion Board SD Card Expansion

ARDUINO W5100 Ethernet Network Expansion Board SD Card Expansion

Description:
- Arduino Ethernet  W5100 network expansion module, which can make Arduino become easy Web server or reading or writing digital and analog interface through network control. Can directly use Ethernet files in IDE to realize a simple Web server
- This verison board supports Mini SD card(TF card) read or write
- This expansion adopts folding design, can be directly plugged into Arduino, at the same time other expansion board can also be plugged in

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