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.

Working with speech

Earlier in this chapter, we generated music melodies using the Micro:bit. The Micro:bit can also be used to generate speech. This means we can generate words, sentences, and even poems using the Micro:bit. We will use a speech library to generate speech using the Micro:bit. Let us try generating a simple speech message using the speech library:

import speech
from microbit import *
speech.say("Hey!")
sleep(500)
speech.say("How are you friend")
sleep(1000)

This program will generate the speech Hey! How are you friend? We can hear the sound from the internal speaker or any external speaker connected to the Micro:bit.

The speech that’s generated by the preceding program does so using the Text-to-Speech (TTS) default settings. The TTS conversion in the Micro:bit is done with Software Automated Mouth (SAM), which was originally released in 1982 for the Commodore 64. More details about SAM are available at https://simulationcorner.net...
