MicroPython Cookbook

By: Marwan Alsabbagh

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.

Creating a function to enable speaker output

In this recipe, you will learn how to create a function that, when called, will enable the speaker. If you don't enable the speaker before audio playback, then it will be played through pin A0, which can have a headphone connected to it.

This project will use the speaker on the board instead of headphones, so we will need this function to enable the speaker at the start of our script. Beyond showing you how to enable the speaker, this recipe will also introduce you to ways of digitally controlling input/output pins.

Getting ready

You will need access to the REPL on Circuit Playground Express to run the code presented in this recipe.
