Practical Python Programming for IoT

By: Gary Smart

Overview of 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.

Summary

In this chapter, we looked at four different way of structuring a Python program that interface with electronics. We learned about an event-loop approach to programming, two variations on a thread-based approach – callbacks and a publisher-subscriber model – and finished by looking at how an AsyncIO approach to programming works.

Each of the four examples we covered was very discrete and specific in its approach. While we briefly discussed the relative benefits and pitfalls of each approach along the way, it's worth remembering that in practice, your projects will likely use a mixture of these (and potentially other) approaches, depending on the programming and interfacing goals you are trying to achieve.

In the next chapter, we will turn our attention toward IoT platforms and present a discussion of the various options and alternatives that are available for building IoT programs.
