M5Stack Electronic Blueprints

By: Don Wilcher

Overview of this book

As an embedded systems developer or an IoT developer, you can often face challenges in maintaining focus on prototyping a product concept while using a specific high-level programming language for implementation. To overcome these challenges, the M5Stack Core platform uses an ESP32 microcontroller and block code that allows you to focus on product creation and application instead of the high-level programming language. M5Stack Electronics Blueprints presents various design and prototyping approaches as well as UI layout and electronics interfacing techniques that will help you to become skilled in developing useful products effectively. This book takes you through a hands-on journey for a better understanding of the ESP32 microcontroller and the M5Stack Core's architecture. You’ll delve into M5Stack Core topics such as electronic units, light, sound, motion devices, interfacing circuits, SNAP circuit kits, Arduino applications, and building Bluetooth and Wi-Fi IoT devices. Further, you’ll explore various M5Stack core applications using a project-based learning method, including the fascinating 32-bit microcontroller device technology. By the end of this book, you’ll be able to design and build interactive, portable electronic controllers, IoT, and wearable devices using the M5Stack Core.

Interacting with an angle sensor unit

The angle sensor unit uses a basic 10 Kiloohm (KὨ) potentiometer for rotary adjustment of providing control signals. A potentiometer is a three-terminal electrical component that provides a range of resistance values. The primary function is to provide voltage division of an attached voltage supply source to an electrical circuit. Figure 2.23 shows a typical potentiometer:
