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.

Questions

As we conclude this chapter, here is a list of questions for you to test your knowledge regarding this chapter's material. You will find the answers in the Assessments section of the Appendix:

  1. With our first IFTTT Applet, where we monitored the temperature, why did we use a different high and low temperature value to trigger our Applet and send an email?
  2. What was the advantage of using an intermediary service such as dweet.io with our IFTTT Webhook service?
  3. What are some of the core differences between IFTTT and Zapier?
  4. Can you control your Raspberry Pi from a ThingSpeak dashboard?
  5. In relation to data, what is the limitation of the IFTTT Webhook service when used as an action (that is, on the That side of an applet)?
  6. You want to prototype the switching on and off of an over-the-counter smart light bulb based on a Raspberry Pi's GPIO pin state. What platforms could you use?
