Overview of this book

MicroPython is an open source implementation of Python 3 that runs in embedded environments. With MicroPython, you can write clean and simple Python code to control hardware instead of using complex low-level languages such as C and C++. This book guides you through all the major applications of the MicroPython platform to build and program projects that use microcontrollers. This MicroPython book covers recipes that will help you experiment with the programming environment and hardware programmed in MicroPython. You'll find tips and techniques for building a variety of objects and prototypes that can sense and respond to touch, sound, position, heat, and light. This book will take you through the uses of MicroPython with a variety of popular input devices and sensors. You'll learn techniques to handle time delays and sensor readings, and apply advanced coding techniques to create complex projects. As you advance, you'll deal with Internet of Things (IoT) devices and integration with other online web services. In addition to this, you'll use MicroPython to make music with bananas and create portable multiplayer video games that incorporate sound and light animations into the gameplay. By the end of this book, you'll have mastered the tips and tricks to troubleshoot your development problems and take your MicroPython project to the next level.

Converting MP3 files to WAV files

In this recipe, we will learn how to convert an MP3 file to a WAV file, which can then be played on the Circuit Playground Express. MP3 files are one of the most popular sound file formats around. This recipe is very useful for when you have an audio clip that you want to include in your embedded project, but need to get it in the right format so that it can play back correctly.

Getting ready

You will need to download and install the open source audio editing software, Audacity. It is available for Windows, macOS, and Linux.
