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.

Reading the robot car's data from the cloud

In Chapter 15, Connecting Sensory Inputs from the Robot Car to the Web, we were able to send the distance sensory data to the cloud using the website https://thingsboard.io/. We ended by showing an analogue meter displaying the distance value. In this section, we will dig a little deeper into the analogue widget by customizing it.

Changing the look of the distance gauge

This is how we change the look of the distance gauge:

  1. Log into your ThingsBoard account
  2. Click on DASHBOARDS
  3. Click on the ROBOTEYES title
  1. Click on the orange pencil icon in the bottom-right corner of the screen
  2. You will notice that the distance analogue dial has changed (see the following screenshot)
  3. For one...
