Arduino Ethernet Shield Real Time Clock Frequency (Clock Speed) : 16Introduction : Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the 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. Use the Ethernet Library to write sketches which connect to the internet using the shield. The ethernet shield connects to an Arduino board using long wire wrap headers which extend through
