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.

Controlling the blue and red LEDs

The ESP8266 comes with two LEDs: one that's red, and another that's blue. Both of these LEDs can be controlled from the scripts you load on the board. This recipe will show you how you can control each one, and will end with an animation that blinks the lights between red and blue.

The techniques that are shown in this recipe can be used in your own projects whenever you want to signal some sort of status to your users. You might want to have a blinking blue light when you are scanning for a Wi-Fi network, or to light up the red light when your board has lost its network connectivity.

Getting ready

You will need access to the REPL on the ESP8266 to run the code presented in this...
