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 Bluetooth messenger device

You now have a working knowledge of using the Nordic Semiconductor nRF Toolbox app by setting up the app on a mobile device such as a smartphone or tablet. With the toolbox running effectively on your selected mobile device, you were able to detect and pair with the toolbox. The detection and pairing process was quite seamless, and as shown in Figure 7.13, you were able to send a text message to the M5Stack Core2. Figure 7.16 provides a use-case diagram of the M5Stack Core2 as a basic Bluetooth messenger device:

As observed in Figure 7.16, the user or actor initiates the messaging by entering or typing an ON message into the UART utility service profile of the Toolbox app. The message is sent or transmitted to the other actor by the M5Stack Core2 to the smartphone or tablet receiving the text. This send-and-receive process is the primary...
