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.

What is a Snap LED MC module?

The Snap LED MC module is a dual seven-segment LED display driven by a microcontroller and supporting electronic parts. The microcontroller is a PICAXE-08M2 integrated circuit. The PICAXE-08M2 microcontroller is an eight-pin integrated circuit. The chip has flash memory, thus allowing it to be programmed easily. Figure 4.5 shows a photo of a PICAXE-08M2 microcontroller:

The LED MC is pre-programmed with 21 arcade-based games. Some of the game titles are binary coded decimal, changing speed, the baseball game, and home run derby. The arcade games are accessible using a selector switch and a sequence of instructions. Several snaps provide various electrical control functions that allow the LED MC to provide the arcade games previously listed. Figure 4.6 shows the LED MC with its snap functions:
