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 a touch control relay controller

You now have the technical skills and knowledge from the previous project to build a touch control relay controller. The concept for the touch control relay controller is that the M5Stack Core2 will provide a nice UI to operate the Freenove Projects kit onboard transistor relay driver. The Freenove Projects kit onboard transistor relay driver circuit is built using five basic electronic/electromechanical components. The five basic electronic/electromechanical components are two fixed resistors, an LED, an NPN transistor, a silicon diode, and a single-pole double-throw (SPDT) electromechanical relay. An electronic circuit schematic diagram is illustrated in Figure 6.32:

The convenience that the Freenove Projects kit provides is that the transistor relay driver is completely populated and assembled on the PCB. Such convenience allows M5Stack Core2 controller...
