In the last section, we built our first circuit on a breadboard by following a series of illustrated steps. In this section, we will learn about schematic diagrams, which is a formal way of documenting and describing an electrical circuit. These are the diagrams you find in electronic texts and datasheets.
We will learn how to read a simple schematic diagram and how it relates back to the breadboard layout we just created. Understanding how the two relate, and especially being able to create a breadboard layout from a schematic diagram, is an important skill you will need to develop as you continue your electronics and IoT journey.
The electronic circuits and schematic diagrams we will be seeing and working with throughout this book will be relatively simple as far as schematic diagrams are concerned. We will address important concepts and component symbols as we encounter them on a case-by-case basis. For our...
