CHAPTER 2 ■ INTERNET CONNECTIVITYFinal 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.Figure 2-6. Log messages from Arduino
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.
