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.

Designing printed circuit boards

PCBs are designed using EDA software, similar to, and in a lot of cases the same as, the ones used for schematic design. The primary difference here is that you need to place the components and connect them using circuits. All of this has to fit within the dimensions of your chosen board, so PCBs have layers. The board itself is non-conductive, with the circuits etched on using copper. The connections between components are called traces.

The copper traces are thinner than the wires that you worked with during the prototyping phase. Since traces are electrical conductors, they mustn’t cross each other. This is called a collision. You may notice from electrical schematic diagrams that wires jump over each other. That is the same principle that applies here. However, since traces are etched onto the PCB, they can’t jump over each other on the same plane or layer. Instead, they jump to a different plane and then continue their journey...
