Ethernet Shield

Introduction

Ethernet Shield instantly enables internet connectivity for Arduino projects. An on-board Wiz5100 ethernet controller handles up to four TCP and UDP connections, just stack it onto an Arduino to create your own networked devices. Easily check connection status with on board indicator lights. Extend your design further with two extra rows of pin header that connect to shields and prototyping boards.

Features

• Standard Arduino and Arduino Mega compatible
• Arduino Ethernet Library compatible
• Standard RJ45 ethernet Jack
• 16K byte internal buffer
• Indicator LEDs for all functions
• Easy to access reset button
• Standard pin headers for 0.1" grid prototyping boards
• Up to 4 TCP/UDP network connections

Usage

Hardware Installation

Connect the ethernet shield with internet via RJ45 connector, and Arduino with PC via USB cable. Insert ethernet shield onto Arduion board:

Software

• Open the Arduino IDE(1.0), open the WebServer example in the Ethernet library:

• Select the corresponding Arduino board, like Arduino UNO or Duemilanove or others, in: Tools- Board; Select COM port you are using in: Tools- Serial port.
• Open your web browser and input the web address:192.168.1.177, you will see the operation result of the arduino board as web server:
