  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 9.

 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 9
