Most IoT device developments use the Arduino board as the board target. Since Arduino shares schemes and designs, the makers make their own boards with custom Arduino models. Arduino models range from the basic Arduino board model to the advanced Arduino board model. The Arduino board is the best choice to introduce IoT development.

In this section, we will explore how to use Arduino Yún to interact with AWS IoT. For further information about Arduino Yún, I recommend that you read the official documentation at https://www.arduino.cc/en/Guide/ArduinoYun.

To work with AWS IoT using Arduino Yún, we perform the following steps:

1. Install the Arduino software
2. Connect Arduino Yún to a network through Ethernet or a Wi-Fi module
3. Configure Arduino Yún for AWS IoT SDK
4. Build a program for Arduino Yún

Each step will be performed...
