Sensing and actuating on IoT devices

In this section, we will learn how to sense and actuate on IoT devices. This part is important because we can gather data through sensor devices or interact with the environment through actuator devices. For testing, I use Arduino, from Arduino.cc, and Raspberry Pi boards.

Sensing and actuating on Arduino devices

Most Arduino development uses Sketch. This is a simple programming language for building Arduino applications. If you have experience in C/C++, you'll be familiar with the programming syntax.

To start your development, you can download Arduino software from https://www.arduino.cc/en/Main/Software. After that, read about Arduino API at http://www.arduino.cc/en/Reference/HomePage.
