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 RGB LED unit

The RGB LED unit has three individual LEDs: red, green, and blue emitters. You can control each LED individually or simultaneously using code. You can also control the RGB LED unit’s intensity. With the M5Stack Core, you can create visually appealing light effects using the RGB LED unit. Figure 2.5 shows the RGB LED unit. To program the RGB LED, you will use the UIFlow Blockly code software discussed in Chapter 1.

Figure 2.5 – The RGB LED unit

The RGB LED unit consists of three individual pixels consisting of red, green, and blue colors. Each pixel is operated by an electronic control circuit. The colored pixels and electronic control circuit are packaged inside an RGB chip. The RGB chip is a surface mount device (SMD) of the 5050 variant component footprint. The footprint is the mechanical package of the electronic SMD device. You can see a picture and mechanical package dimensions of the RGB chip in Figure...
