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 LED dimmer controller

This final project demonstrates controlling a discrete LED’s light intensity with a varying output control voltage. The concept controller consists of three electronic components: the M5Stack Core2, the Freenove Projects kit Arduino Uno compatible, and a discrete LED circuit. The concept of an LED dimmer controller block diagram is shown in Figure 6.39:

Note

Applying an adjustable voltage source affects the electrical current flowing through an LED, thus changing the light intensity of the optoelectronic component.

You will use a slider UI to adjust the light intensity of the LED. The equivalent electronic component used to change a basic light source’s light intensity is a rheostat. A rheostat is a variable resistor that can change the electrical current through adjusted resistances. Today’s basic light source is the LED. The M5Stack...
