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 alarm device

In this section, you will wire a Snap Circuits alarm device that is controlled by the M5Stack controller. The alarm circuit device will be operated by the electromechanical relay module used in the previous project. The electromechanical relay module’s switching action will be influenced by the M5Stack Core’s UiFlow Blockly code. The UiFlow Blockly code will alternately switch the Snap Circuits alarm device on and off. The switching contact of the electromechanical relay module will provide a symmetric-based alarm sound, thus getting the attention of a bystander. The main Snap Circuits module that will provide the audible sound is the ALARM IC. Figure 4.21 shows the Snap Circuits alarm IC and electrical connections.

Note

The Snap Circuits alarm IC module uses a custom Application-Specific Integrated Circuit (ASIC) to produce several audible sounds.
