Webduino

Project forked from 1.4.1 of http://code.google.com/p/webduino/ By Ben Combee

This is an Arduino-based Web Server library, originally developed for a class at NYC Resistor. It's called Webduino, and it's an extensible web server library for the Arduino using the Wiznet-based Ethernet shields. It's released under the MIT license allowing all sorts of reuse.

I've got a few examples up right now -- the Buzz example interfaces with Zach's Danger Shield allowing you to remotely start and stop the speaker. We had a room full of students pinging my Arduino board on Saturday, buzzing me while I was lecturing. It was fun. The big Demo example shows how to setup an HTML form running on the device where you can read and write pins.

I hope to add a few more examples in the next few weeks, including a web-enabled fridge sign using a serial LCD and how to serve things other than just HTML text from the device. I also need to work on more documentation and finishing up my slides.

Features

• URL parameter parsing
• Handle HTTP Methods, e.g. GET, POST
• Web Forms
• Images
• JSON/RESTful interface

Installation Notes

With Arduino 0022, add the Webduino folder to the "libraries" folder of your sketchbook directory.

You can put the examples in your own sketchbook directory, or in hardware/libraries/webduino/examples, as you prefer.

If you get an error message when building the examples similar to "WebServer.h not found", it's a problem with where you put the Webduino folder. The server won't work if the header is directly in the libraries folder.
