Practical Python Programming for IoT

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.

Triggering an IFTTT Webhook

Now that we have created our IFTTT Applet, we need to take a few more steps to learn how to trigger our Webhook. These steps boil down to knowing where to navigate to within IFTTT to discover your unique Webhook URL.

Here are the steps we need to follow:

  1. First, we need to navigate to the Webhooks page. There are a couple of ways we can do this, and I'll leave it up to you which route you take:
    • Navigate your web browser to the Webhook services URL; that is, ifttt.com/maker_webhook.
    • Alternatively, the navigation steps to take to get to this web page are as follows:
      1. Click on the profile avatar icon (as shown previously in Figure 13.2).
      2. In the menu that appears, choose the My Services item (refer to Figure 13.3).
      3. On the page that appears, find and click on the Webhooks item.

Irrespective of the path you take, you will see the page shown in the following screenshot:
