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.

Performing an HTTP request using raw sockets

This recipe will use the socket library that comes with both MicroPython and Python to perform an HTTP request. We will create a function that receives a URL as its input and returns the response from the requested web server after performing the HTTP request. We will also create a function that can parse a URL and return the hostname and path components of the URL. These pieces will be needed to perform the HTTP request.

There's a whole class of MicroPython projects that will want to connect to web servers on the internet and fetch different results. You will see one way to do this using the socket library, which gives you direct access to TCP sockets to read and write bytes of data from them.
