Since now on, it will be easy to provide your Arduino with Internet connectivity by using this shield. The shield sports a TCP/IP stack manager, in order to free up the Arduino from some basic tasks. It’s also essential to equip the board with a library, that communicates with the TCP/IP manager and makes it easier to program the Arduino and to let  it communicate with other computers via the Internet.   The WiFi shield Despite the proliferation of hardware to connect Arduino with the web, and especially despite YUN, we considered useful to design and propose a new WiFi shield for Arduino, which replaces the one already presented. This time we indeed added an interface processor  that manages the TCP/IP protocol: a definitely too challenging task for Arduino. Anyway a network interface card becomes really useful if it’s driven by software which simplifies as much as possible its use, especially in a context of reduced hardware resources such as with [...]
