+  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
+ 
+ created 25 Nov 2012
