WebServer

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.
