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.

Overview of the IoT Christmas tree

Before we commence our chapter by building circuits and looking at code, let's take a moment to understand what our IoTree will do and how we will be building it. The tree pictured in Figure 14.1 is representative of what you could create after completing this chapter:

Figure 14.1 – IoTree example

Now, I'll need to let you know up front that we're only covering the electronics and programming of the IoTree. You'll need to apply your initiative and bring your maker skills to the table to build the tree and bring it to life. I suggest using a small table-top Christmas tree since part of our build involves a servo to shake the tree. Our hobby-grade servo is powerful enough to shake a small tree; however, it's unlikely that it could shake a full-size Christmas tree (you'll need to research and get a more powerful servo if you aspire to upgrade our build to a larger tree – and please send me...
