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

Well done on getting this far, as there has certainly been a lot to get our heads around! As a recap, we explored common numbering schemes for referencing GPIO pins and reviewed popular GPIO libraries for Python. We also looked at the various interfacing methods used to connect electronics to your Raspberry Pi and performed a practical exercise to add an ADC to your Raspberry Pi and use it to visually explore PWM concepts with an LED and the PiScope logic analyzer.

Your understanding of the fundamental concepts we explored and experimented with during this chapter will help you to understand how your Raspberry Pi interfaces to electronic components and devices and has provided you with a first-hand appreciation of how we interact with analog components (for instance, our potentiometers) and complex devices (that is, our ADS1115). We will be using and building on many of these fundamentals as we progress through the remainder of this book.
