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.

Running the IFTTT and LED Python program

In this section, we will run our program and obtain a unique thing name and URL for use with the dweet.io service.

Here are the steps to follow:

  1. Run the code that can be found in the chapter13/dweet_led.py file in a Terminal. You will receive an output similar to the following (your thing name and therefore your URLs will be different):
(venv) $ python dweet_led.py
INFO:main:Created new thing name 749b5e60
LED Control URLs - Try them in your web browser:
On : https://dweet.io/dweet/for/749b5e60?state=on
Off : https://dweet.io/dweet/for/749b5e60?state=off
Blink : https://dweet.io/dweet/for/749b5e60?state=blink

As we mentioned previously, chapter13/dweet_led.py is an exact copy of the same program we discussed in Chapter 2, Getting Started with Python and IoT. If you need more context around how this program works, please revisit that chapter and the code discussion contained therein.

  1. Keep your Terminal open with the program running...
