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 inverting switch

With an understanding of the M5Stack Core2’s touchscreen setup and capabilities, you are now ready to build a touch control inverting switch. A touch control inverting switch is a digital device whereby a simple touch of a UI button will turn off an LED. Inverting switches aid automation systems whereby detecting an electrical contact open status of a normally closed electronic switch provides an inverted output state. Industry safety devices such as a pressure mat switch stop an industrial process when a machine operator stands on it. Upon standing on a pressure mat switch, its normally closed (NC) contacts are inverted or open, thus turning off the industrial process. With the industrial process stopped, a maintenance technician can work on an automated machine safely.

The touch control inverting switch consists of three primary components: the M5Stack Core2, an Arduino Uno compatible, a digital inverter IC, and an LED. The M5Stack...
