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.

In this chapter, you learned about shields and carriers, and then worked on some projects using both a shield and a carrier. This was important because you got to focus on the code that you needed to write to collect data without having to fiddle with breakout boards, breadboards, and wires that could come loose and lead to a lot of time spent debugging your code. With the MKR IoT Carrier, you were also able to display the readings on the OLED screen. This is useful for communicating information to users without asking them to connect the device to a computer for serial output. We are collecting data but not storing it.

In the next chapter, we will discuss various strategies for storing this data locally, especially given that the MKR IoT Carrier and the MKR ENV Shield both come with SD card slots.
