WiFi Web Server LED Blink
A simple web server that lets you blink an LED via the web.
This sketch will create a new access point (with no password).
It will then launch a new server and print out the IP address
to the Serial monitor. From there, you can open that address in a web browser
to turn on and off the LED on pin 13.
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 13
