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 counter

The touch control counter is a fascinating project where a seven-segment LED display feature will be built and demonstrated to the reader. There are four components required to make the touch control counter operational. The four touch control counter components are the M5Stack Core2, the Freenove Projects kit Arduino Uno compatible, a transistor relay driver circuit, and a four-digit seven-segment LED display. Figure 6.24 shows a touch control counter block diagram:

The M5Stack Core2 provides a UI for operating the Freenove Projects kit onboard transistor relay driver circuit. The electromechanical relay single pole single throw normally open (SPST NO) contact provides a ground or low-control signal to the Freenove Projects kit Arduino Uno compatible. The Arduino Uno compatible will provide the latch, data, and clock signals to operate the four-digit seven-segment LED display...
