Ethernet Shield for Arduino – a walkthrough

Project description

The Arduino board can be connected to the Internet using this Ethernet Shield which is based on the WIZNET W5100 Ethernet chip . The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. WIZNET W5100 is the classic one , widely used by Arduino.CC . WIZNET W5500 is used by Arduino.ORG & is referred as Ethernet shield 2. We shall use the classic Ethernet shield W5100 in this post. The shield has long pin headers to plug on the Arduino (UNO or MEGA). Other shields can be stacked on top of this board.There is an onboard micro-SD card slot, which can be used to store larger…
