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.

Building an M5Stack Core Snap Circuits counter with a sound device

In this final project, you will use the knowledge obtained on building Snap Circuits to construct a counting sound device. You will learn how to repurpose the alarm device to work with the LED MC. The project’s concept of reuse consists of controlling the counting feature of the LED MC and adding an audible sound. The audible sound resembles a machine gun when the ALARM IC module is triggered. The LED MC will rapidly display numbers based on the module’s S-IN input being triggered for a specified time duration. You will make a slight modification to the M5Stack Core’s UI to reflect the name of the project. The concept block diagram for the M5Stack controller counting sound device is shown in Figure 4.31:
