Internet of Things Programming Projects

By: Colin Dow

Overview of this book

The Internet of Things (IOT) has managed to attract the attention of researchers and tech enthusiasts, since it powerfully combines classical networks with instruments and devices. In Internet of Things Programming Projects, we unleash the power of Raspberry Pi and Python to create engaging projects. In the first part of the book, you’ll be introduced to the Raspberry Pi, learn how to set it up, and then jump right into Python programming. Then, you’ll dive into real-world computing by creating a“Hello World” app using flash LEDs. As you make your way through the chapters, you’ll go back to an age when analog needle meters ruled the world of data display. You’ll learn to retrieve weather data from a web service and display it on an analog needle meter, and build a home security system using the Raspberry Pi. The next project has a modern twist, where we employ the Raspberry Pi to send a signal to a web service that will send you a text when someone is at the door. In the final project, you take what you've learned from the previous two projects and create an IoT robot car that you can use to monitor what your pets are up to when you are away. By the end of this book, you will be well versed in almost every possible way to make your IoT projects stand out.

Working with the Servo Control Code to Control an Analog Device

Continuing our journey to combine the elegance of an analog meter with the accuracy of digital data, we will take a look at what we've learned in the previous two chapters and build an IoT weather dashboard with an analog meter display.

Make sure that you have the circuit from Chapter 5, Controlling a Servo with Python, wired up before you start this chapter.

This dashboard will display wardrobe suggestions based on the outside temperature and wind speed. We will also use an LED on our dashboard to indicate whether or not we should take an umbrella with us.

The following topics will be covered in this chapter:

  • Accessing weather data from the cloud
  • Controlling the servo using weather data
  • Enhancing our project
