About this book

The age of connected devices is here, be it fitness bands or smart homes. It's now more important than ever to understand how hardware components interact with the internet to collect and analyze user data. The Internet of Things (IoT), combined with the popular open source language Python, can be used to build powerful and intelligent IoT systems with intuitive interfaces.

This book consists of three parts, with the first focusing on the "Internet" component of IoT. You'll get to grips with end-to-end IoT app development to control an LED over the internet, before learning how to build RESTful APIs, WebSocket APIs, and MQTT services in Python. The second part delves into the fundamentals behind electronics and GPIO interfacing. As you progress to the last part, you'll focus on the "Things" aspect of IoT, where you will learn how to connect and control a range of electronic sensors and actuators using Python. You'll also explore a variety of topics, such as motor control, ultrasonic sensors, and temperature measurement. Finally, you'll get up to speed with advanced IoT programming techniques in Python, integrate with IoT visualization and automation platforms, and build a comprehensive IoT project.

By the end of this book, you'll be well-versed with IoT development and have the knowledge you need to build sophisticated IoT systems using Python.

Section 1: Programming with Python and the Raspberry Pi

In this first section of our journey, our primary focus will be on the Internet part of IoT.

We'll start by learning how to properly set up your Python development environment, before exploring and playing with a variety of networking techniques using Python to build network- and internet-connected services and applications. We will also create simple web user interfaces that work with the techniques and examples we will learn about.

However, I am sure if you are reading this book you are eager to jump right in, learn about and play with electronics, and start building and tinkering. I know I would be! So, Chapter 2Getting Started with Python and IoT is dedicated to building a simple internet-connected IoT project from the ground up – electronics and all – so that we have a reference example for later chapters (and something to tinker with!).

Let's get started!

This section comprises the following chapters:

  • Chapter 1, Setting Up Your Development Environment
  • Chapter 2, Getting Started with Python and IoT
  • Chapter 3, Networking with RESTful APIs and Web Sockets using Flask
  • Chapter 4Networking with MQTT, Python, and the Mosquitto MQTT Broker
