Ethernet Shield
The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100/W5200 ethernet chip providing a network (IP) stack capable of both TCP and UDP. Use the Ethernet library to write sketches which connect to the internet via a RJ45 Ethernet jack.
