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.

Creating an access point and web server with an M5Stack Core controller

In this final chapter project, you will build an access point and web server using an M5Stack Core controller and a smartphone. You will use the M5Stack Core to create an access point to connect and control a wireless device. The WAP will be accessible with an SSID and URL network address. The smartphone will allow access to the wireless network by connecting to the M5Stack Core 2 WAP SSID. The result is connecting to a web server that allows you to control an external device wired to an M5Stack Core controller. The concept for the WAP and web-server-based controller is shown in Figure 8.29.
