FYP2 - Week 2

ARDUINO ETHERNET SHIELD

This shows how to set up an Arduino with Ethernet shield as a web server. The web servers in this 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).

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

Hardware Components

The hardware required for following this series of tutorials is:

• An Arduino board such as the Arduino Uno
• An Arduino Ethernet shield
• An Ethernet cable, wired straight for connecting to your network router
• A USB cable for powering and programming the Arduino
• A micro SD card, e.g. a 2Gb card that is SPI compatible – only required for some of the servers
• A computer with a micro SD card slot or a card reader with a micro SD card slot – only required for SD card servers

Hardware Setup

Before starting:

1. Plug the Ethernet shield into the Arduino Uno R3, connect it to the network and test it.
2. Test the SD card in the Ethernet shield.
