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.

Working with SMS

SMS is a text-based two-way communication method. It is useful because it works well in the absence of internet connectivity, and it is used in a lot of applications where you want the microcontroller to do something, or where you want the microcontroller to report the status of something.

Let’s consider the first instance where you would like a microcontroller to receive an SMS.

Project 2 – Receiving an SMS

Take the following steps to display the content of any SMS messages received on the microcontroller. The code for this section is available at GitHub (

  1. Connect the dipole antenna to the MKR GSM. This is the antenna that comes with the MKR GSM purchased from the Arduino Store.
  2. Insert the SIM card into the holder.
  3. Connect the negative pin of the 5V power supply to the GND pin of the microcontroller.
  4. Connect the...
