Arduino WiFi Shield

Arduino WiFi Shield allows you to connect your Arduino board to the Internet wirelessly. In the previous chapter, you learned how to connect the Arduino board to the Internet using an Ethernet shield with a wired connection. Unlike a wired connection, a wireless connection provides us with increased mobility within the Wi-Fi signal range, and the ability to connect to other Wi-Fi networks automatically, if the current network loses connection or has insufficient radio signal strength. Most of the mechanisms can be manipulated using the Arduino Wi-Fi library, a well-written piece of program sketch. The following image shows the top view of an Arduino WiFi Shield. Note that two rows of wire wrap headers are used to stack with ...
