Overview of this book

This book is a one-stop guide for learning BBC Micro:bit with MicroPython, exploring many hardware components and programming techniques to provide detailed insights into developing practical applications with the Micro:bit. It will also show you how hardware components can be manipulated using a combination of Micro:bit and MicroPython for developing practical projects. BBC Micro:bit in Practice will help you gain a holistic understanding of the BBC Micro:bit platform and MicroPython programming, guiding you through mini projects aimed at developing practical knowledge of circuit design and writing programs. You’ll learn how to write programs for working with built-in LEDs and buttons, interfacing external LEDs, buttons, motors, buzzers, and much more. You’ll also work with built-in radio, speakers, accelerometer, and a compass. You’ll dive into concepts related to the Micro:bit filesystem, interfacing external displays, and working with libraries in detail before exploring sewable circuits and wearable technology. After reading this Micro:bit book, you’ll understand how to apply principles in electronics and MicroPython to create interesting real-life projects from scratch.

Breakout boards

The General Purpose Input Output (GPIO) pins of the Micro:bit are extremely narrowly printed on the edge connector. It is difficult to use them directly, and soldering can ruin the board. So, many organizations have developed special products that make the GPIO pins of the Micro:bit easily accessible. These products are known by various names, such as breakout boards, GPIO expanders, I/O extensions, and edge connectors. The following are the URLs of the web pages for such products:

I urge you all to procure one of these or any other edge connector of your choice, as we will need these for the demonstrations in this book.

I, too, own a couple of them, as shown in the following photos:

Here, we have Micro:bit V1 and V2 inserted into the edge connectors:

In the following section, we will get acquainted with a software program, Fritzing, that will help us visualize circuits.
