Arduino + Shield Ethernet

Realiza un programa utilizando arduino + la shield ethernet  y se trata acerca de un servidor, lo que hace es que controla 3 leds desde un servidor, prendes cada uno de ellos y aumentas o bajas su intensidad.

Material Utilizado:

Arduino +Shield Ethernet
3 leds
3 resistencias
1 cable ethernet
