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.

Interacting with an IR remote unit

The IR remote unit is an electronic photoelectric sensor capable of detecting infrared signals. The IR remote unit has an infrared emitter and receiver pair circuit packaged inside the electronic sensor unit. The IR remote unit is shown in Figure 2.16. The IR remote uses an IRM-3638 three-pin integrated circuit (IC). As shown in Figure 2.17, the IRM-3638 IC is responsible for detecting and decoding or demodulating IR signal data.

There is a photodiode used to transmit IR data from the M5Stack Core. The transmit ability of the IR remote unit provides the emitter operation of the photoelectric sensor device. Therefore, you can quite easily build a portable handheld IR remote tester using the M5Stack Core and this photoelectric sensor device. You will be exploring...
