Arduino is an open source physical computing platform based on a simple microcontroller and a free user friendly software development environment that implements the Processing language. The WiFi shield brings WiFi and true wireless connectivity to the your Arduino projects.
Get Your Wireless Internet Connection with the Arduino WiFi Shield!
This is the shield you need to get Wi-Fi connectivity to your Arduino-based project! The Arduino WiFi shield is an add-on board that mates a ZeroG WiFi module to an Arduino board and allows for wireless connections between your Arduino and the Internet.
The Arduino WiFi shield provides 802.11b connectivity and is a direct drop-on plug-and-play solution to your Arduino Duemilanove or Diecimila; it talks to the Arduino on the SPI interface (max speed 25MHz) and has low power usage: 165mA transmit and 85mA receive.
The shield is capable of connecting to wireless networks (including WEP and WPA/WPA2 encryption) and also of setting up its own network, for instance to broadcast a website.
You can make use of the available WiServer code which allows you to do fancy stuff like run server and client concurrently. The WiServer is an easy-to-use HTTP library developed by Mark Patel specifically for use with the WiShield. It enables a WiShield-equipped Arduino to act as a web server and/or a web client while requiring minimal code in the sketch.
So what are you waiting for? Set up your wireless connection on your projects with the Arduino WiFi Shield!
For an Arduino with built-in WiFi connectivity that does not require the use of a WiFi shield, check out the Arduino WiFi BlackWidow.
