Overview of this book

In our modern, internet-connected world, where billions of devices constantly collect and send data to systems to be stored and processed, it’s surprising how the intricacies of data transmission and storage are often overlooked in the IoT domain. With Arduino Data Communications, you'll bridge the knowledge gap and become an expert in collecting data from IoT sensors, transmitting data, and configuring your own databases. This book is an exploration of IoT’s inner workings, guiding you through the process of setting up an end-to-end system that you can employ to prototype your own IoT solutions, using easy-to-follow examples. It begins with a general overview of the Arduino ecosystem, acquainting you with various sensors and shields and unveiling the art of data collection. You’ll then explore data formats and methods to store data, both locally and on database servers. As you progress through the chapters, you’ll learn how to set up REST and MQTT infrastructure to communicate with databases and get hands-on with LoRaWAN, Ethernet, cellular, HC-12, and RS-485. The final chapters are your training ground for real-world projects, imparting the essential knowledge you need to tackle complex challenges with confidence. By the end of this Arduino book, you'll have seamlessly configured an end-to-end system, all while immersing yourself in practical scenarios that bring the world of IoT to life.

Implementing a REST API using Python

If you are familiar with Python programming, then you might find yourself wondering whether you can write your APIs using Python instead of JavaScript. The answer is in the affirmative, and we are going to do just that.

We will make use of Python 3 and FastAPI to create the REST API that we need. FastAPI is a Python framework for building APIs. Python can be downloaded at

Follow these steps to confirm that you have Python installed:

  1. The first thing that you need to do is confirm that you have a version of Python installed that is at least 3.7. You can do that by running the following command from your CLI:
    python -V

    You should get an output similar to the following if you have Python installed:
