Mastering IOT

By: Colin Dow, Perry Lea

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. We’ll begin our journey with an introduction to Raspberry Pi and quickly jump right into Python programming. We’ll learn all concepts through multiple projects, and then reinforce our learnings by creating an IoT robot car. We’ll examine modern sensor systems and focus on what their power and functionality can bring to our system. We’ll also gain insight into cloud and fog architectures, including the OpenFog standards. The Learning Path will conclude by discussing three forms of prevalent attacks and ways to improve the security of our IoT infrastructure. By the end of this Learning Path, we will have traversed the entire spectrum of technologies needed to build a successful IoT system, and will have the confidence to build, secure, and monitor our IoT infrastructure. This Learning Path includes content from the following Packt products: Internet of Things Programming Projects by Colin Dow Internet of Things for Architects by Perry Lea

Reading the robot car's data from the cloud


In Chapter 24, 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 thing, there are three new icons located at the top-right corner of the dial
  4. At the bottom-right corner, the color has changed to light gray as well
  5. You may resize the widget by hovering your mouse over the bottom-right corner
  6. You may also move the widget around the dashboard
  7. The X in the...
