Final Product
To test the application, verify and upload the code to Arduino as discussed in Chapter 1 .
Once the code has been uploaded, open the Serial Monitor window. You will start seeing
log messages as shown in Figure  2-6 .

Arduino Yún Wireless Connectivity (WiFi)
Yún is a more advanced model of Arduino that has been developed for the Internet of
things. For beginners, Arduino Yún may be a little complex as compared to Arduino Uno,
but it comes with built-in Ethernet and wireless capabilities so you do not need to buy
additional shields.
As mentioned in Chapter 1 , this book uses Arduino Uno throughout. This section is
only provided as a reference for readers who already have an Arduino Yún and still want
to follow the real-life prototypes developed in this book. Even though Arduino Yún is
not referenced in rest of the book, the code download contains Arduino Yún-compatible
code as well.
Hardware Required
You do not need any additional hardware to connect Arduino Yún to the Internet, so
Figure  2-7 only includes a diagram of Arduino Yún.
