Web Server
En este ejemplo, con Ethernet Shield y Arduino se crea un servidor web simple. Con la biblioteca Ethernet, su dispositivo podrá responder a una solicitud HTTP. Después de abrir un navegador y navegar a la dirección IP de su escudo Ethernet, su Arduino responderá con HTML para que un navegador muestre los valores de entrada de los seis pines analógicos.
/*
Web Server
A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)
