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.

Melodies

Music is made of melodies. The Micro:bit library is designed with a rich collection of pre-loaded melodies. We can play a simple melody on the Micro:bit using the music module. The module contains 21 melodies. Some of the most popular ones are as follows:

music.DADADADUM
music.PRELUDE
music.RINGTONE
music.BIRTHDAY
music.WEDDING
music.BADDY
music.POWER_UP
music.POWER_DOWN

We can access the complete list using the dir(music) command. Connect your Micro:bit to your PC and run the following simple MicroPython code to play any of these melodies:

import music
music.play(music.BLUES)

We can play multiple melodies by pressing different buttons on the Micro:bit. In the following code, we are playing two different melodies by pressing buttons A and B on the Micro:bit. The following code will play the FUNK melody when button A is pressed and the DADADADUM melody when button B is pressed:

import music
from microbit import *
while True:
    if button_a...
