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.

Randomly selecting cities

In this recipe, we will use the random module to randomly select cities from a fixed list of cities. We first create a global variable called CITIES to store these values. We can then use a specific function in the random module that is for the specific purpose of selecting random items from a list of values.

The recipe will then loop 10 times and make a random selection from the list of cities and output details of the selected city. This recipe will be particularly useful to you whenever you have a project that needs to select a certain option randomly from a fixed list of values. You might, for example, create a dice-rolling MicroPython project that should choose from the values one to six on each roll.
