Part 1 of the Arduino Ethernet Shield Web Server Tutorial

This multi-part tutorial shows how to set up an Arduino with Ethernet shield as a web server. The web servers in this tutorial are used to serve up web pages that can be accessed from a web browser running on any computer connected to the same network as the Arduino.

Some of the Arduino web server pages allow access to the Arduino hardware – this allows hardware to be controlled (e.g. switching on and off an LED from the web page) and monitored (e.g. reading the state of a switch and displaying it on a web page).

The tutorial teaches what is required to build a web server including all the technology such as HTTP, HTML, CSS, JavaScript, AJAX, etc. It starts with the very basics of hosting a simple web page on the Arduino and advances step-by-step from there.
