The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip. The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP. The Ethernet W5100 Shield Network Expansion Board w/ Micro SD Card Slot supports up to four simultaneous socket connections.

This is the most Complete Mega 2560 Starter Leaning Kit for Arduino and it is a more comprehensive kit than other Arduino Kits for Arduino, this kit contains more than 50 kinds of different electronic components, more than 180 components are included. With this kit, we will take you from knowing to utilizing, you will be able to do more experiment, get your more idea into real action without the restriction of hardware and software, and we have carefully prepared a guide book(140 pages Paper Guidebook) and supporting experimental code routine for you, including a total of 37 experiments. Based on our experiments in the Arduino, we added the interaction between the Arduino and processing, so that we can use the Arduino and some simple components to make your own video games, such as gluttony snake, the war, and so on. We will provide you with the Arduino and Processing source program.
