The Arduino WiFi Wireless Shield connects your Arduino to the internet wirelessly. Connect it to your wireless network by following a few simple instructions to start controlling your world through the internet. As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. This means you can learn exactly how it's made and use its design as the starting point for your own circuits.
Check out the reference page of the WiFi library to understand how the shield can easily provide an internet connection to your Arduino board.
