// WiFi Web Server LED Blink
//
// A simple web server that lets you blink an LED via the web.
// This sketch will print the IP address of your WiFi Shield (once connected)
// to the Serial monitor. From there, you can open that address in a web browser
// to turn on and off the LED on pin 5.
//
// If the IP address of your shield is yourAddress:
// http://yourAddress/H turns the LED on
// http://yourAddress/L turns it off
//
// This example is written for a network using WPA encryption. For
// WEP or WPA, change the Wifi.begin() call accordingly.
//
// Circuit:
// * WiFi shield attached
// * LED attached to pin 5
