## Article

This post is a practical demo on controlling an LED from a browser.

Arduino ETHERNET SHIELD is used here. The Browser acts as a CLIENT & the SHIELD acts as a SERVER listening on HTTP PORT 80.

This demo is done on a Local Area Network .This means that the PC from where Browser is operated & the ETHERNET shield both are connected to the same NETWORK. You may have a Router in top of your Network.The Ethernet shield is connected to one of the RJ45 connector of the Router using a STRAIGHT Ethernet cable.The PC from where you start your browser is also connected to the same Router , to another RJ45 connecter or through WIFI , if your Router is WIFI enabled.

Once you connect the RJ45 cable to Ethernet shield, the left LED on RJ45 socket glows Green.This indicates a successful link made to Router.
