This book will introduce you to microcontroller technology. It focuses particularly on two very capable microcontroller boards, the Blue Pill and the Curiosity Nano, and how to connect sensors to them to solve problems and to support everyday life situations. In addition, this book covers the use of light-emitting diodes (LEDs) and liquid-crystal displays (LCDs) for showing sensor information to its microcontroller board users.

Microcontroller boards are practical small computers used for getting information from an environment using sensors. In this book, each chapter will focus on a specific problem to be solved with microcontroller technology, incorporating the use of practical sensors.

Many people from the intended audience would like to start with a microcontroller-based project but they may not know how to begin with it, including what kind of basic hardware and software tools and electronic components they will need to use. This book will cover that.

A chapter in this book introduces you to the field of electronics, examining and reviewing common electronic components that you will use in this book. Another chapter provides an introduction to C and C++, which will be used for coding Blue Pill and Curiosity Nano applications in most of the chapters.

One of the most important aspects of this book is that sensor programming via microcontroller boards is becoming more effective and easier than before because several easy coding libraries support them, which saves time and effort when getting either analog or digital data from them. This book explains common sensor-programming libraries.
