With the offical ethernet library, you can do exactly the same thing as the original one, but at a more affordable price. \u003c\/p\u003e\n\u003cp\u003eThis Ethernet Shield provides an Arduino controller board with internet access. It is based on the Wiznet W5100 ethernet chip. The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. It supports up to four simultaneous socket connections. You can use the Ethernet library to write sketches which connect to the internet using the shield.\u003cbr style=\"font-family: Arial, Helvetica, sans-serif; \"\u003e\n\u003cbr\u003e\nYou can connect the Ethernet Shield to an Arduino board using long wire-wrap headers which extend through the shield.
