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.

Custom melodies

With that, we have a good command of the music module of MicroPython. The melodies that are used in this module are made from various musical notes. A musical note is a symbol that donates musical sounds. A note can also represent a pitch class. Any music melody is made with a correct combination of musical notes. In English music, the notes are A, B, C, D, E, F, and G (the correct order is C, D, E, F, G, A, and B). You can learn more about the chromatic scale at https://en.wikipedia.org/wiki/Chromatic_scale and musical notes at https://en.wikipedia.org/wiki/Musical_note.

The next important aspect of melodies is the octave. The octave is the span between two of the same notes but with double the frequency. It indicates how high or low the note should be played. Octaves are in the range of 0 to 8. The higher the value of the octave, the longer the duration of the note. For example, if the octave is set to 6, then it will last two times longer than octave 3.
