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 littleBits temperature sensor M5Stack Core simulator monitor

In this section, you will take your knowledge of the littleBits proto module and build a physical simulator with a monitor. The technical concept behind this simulator monitor project is to create a physical model of a temperature sensor using a littleBits slide dimmer control. By adjusting the slide dimmer control, a simulated temperature reading will be displayed on the M5Stack Core’s TFT LCD. Upon the slide dimmer control reading exceeding a preset value, the M5Stack Core will turn on the internal LED bar. Figure 5.24 shows the temperature sensor simulator monitor concept block diagram.

You will use the angle unit Blockly code block to capture the analog voltage values generated by the slide dimmer module. The angle unit Blockly code block will be aided by the label code block. The...
