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.

Producing Music and Speech

In the previous chapter, we learned how to work with NeoPixel rings and strips. We also explored how to program the MAX7219-based 7-segment 8-digit display board. We worked with an external MicroPython library for the MAX7219 project and now we are comfortable working with external libraries. We created interesting projects with these cool external displays.

This chapter will explore a new dimension of the Micro:bit by discussing various methods of generating music and speech using Micro:bit. As discussed in the introductory chapters, the Micro:bit V2 has an inbuilt speaker. The programming module comes with inbuilt functions to generate tones and melodies. These can be easily heard using the inbuilt speakers. If we want to hear them louder, we can also connect to any external speaker. In this chapter, we will cover the step-by-step process of dealing with various methods of producing music and speech.

We will explore the following list of topics together...
