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 numbers and letters device

The Snap Circuits Arcade Game numbers and letters device will allow a sequence series of letters and numbers to be displayed on the LED MC. Typically, the selector switch’s C button is used to manually sequence the letters and numbers. You will bypass the selector switch with an M5Stack controller. The M5Stack controller will be wired to an electromechanical relay. The electromechanical relay’s contact will act as the replacement for the C button. A basic block diagram of the controller design is shown in Figure 4.8:

You will use an off-the-shelf electromechanical relay module to act as the switching interface device between the M5Stack Core and the LED MC. This kind of electromechanical relay module device is shown in Figure 4.9. The electromechanical relay module has one set of normally opened switching contracts –...
