Control LED from Web using Arduino

Overview

Here I have controlled an LED from a webpage using Arduino EthernetSheild and Arduino Mega ADK.

First you have to create a server using Arduino EthernetSheild :

• Place your EthernetSheild on the Arduiono Mega and make the connection.
• Connect your Arduino Mega through USB to your laptop, and connect the EthenetSheild to your router using RJ45 cable.
• Open Arduino IDE > File > Example > Ethernet > DhcpAddressPrinter
• Change the MAC Address,(sticker under the EthernetSheild) upload the sketch to your board.
• Open the serial monitor and IP address will be printed.
