Preface

Suppose you are interested in learning new approaches to developing portable electronic controllers to operate electromechanical loads such as a DC motor or introducing new prototyping techniques for interactive product development using littleBits or SNAP circuits as augmentation tools. In that case, the M5Stack Electronic Blueprints book is for you. This book provides coverage of the design, development, and prototyping workflow process of building interactive electronic controllers and IoT device applications. You will learn how to create a physical M5Stack Core controller device based on the ESP32 microcontroller using discrete electronic components, Arduino C/C++, and UIFlow Blockly code (no-code) programming languages.

The ESP32 subsystem is the heart of the M5Stack Core controller. Here, internal circuits, such as a 3W audio amplifier, LED bars, USB-C ports, push button switches, a thin film transistor (TFT) touch screen, and general-purpose input-output (GPIO) ports, are managed by the ESP32 subsystem. You will learn about the structure of the ESP32 subsystem architecture in this book. The ESP32 microcontroller has an internal Bluetooth chipset and Wi-Fi support circuitry. You will learn how to create IoT controllers and scanners using the M5Stack internal Wi-Fi and Bluetooth chipsets. Finally, human computing interaction (HCI)-based techniques for creating effective and aesthetically appealing user interfaces for product engagement will be presented in this book.
