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 class to react to touch events

In this recipe, you will learn how to define a class that can help you use handle touch events on a particular touchpad. When you create an instance of this class, you specify the pad name and a callback function that will be called each time a touch event starts and ends. We can use this class as a building block to have a callback called for each of the four touchpads that will be connected to bananas. You can use this style of code in your own projects, whenever you want to handle a variety of events with a set of callback functions.

Getting ready

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