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.

Breadboards and solderless circuits

We can create circuits with electrical and electronic components such as LEDs, wires, and buttons. We need to use the soldering method to connect them to make them work. However, there is another method we can use to avoid soldering altogether. This method is known as breadboarding or prototyping. We have to use a component known as a breadboard to avoid soldering other components. The following is an image of an MB102-type breadboard:

A Dual In-Line Package Integrated Circuit (DIP IC) is mounted on the breadboard. Let’s see how breadboards are useful. Have a look at the top view of the breadboard:
