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

Using a Python program to control a robot car through the cloud


Being able to see sensory data in a dashboard is pretty impressive. However, what if we wanted to actually control something from our dashboard? In this section, we will do just that. We will start by constructing a simple switch to control an LED on T.A.R.A.S. We will then expand on this and have T.A.R.A.S do its dance from a push of a button over the internet.

Let's start by changing the name of the dashboard from RobotEyes to RobotControl:

  1. In the ThingsBoard application, click on the DASHBOARDS option
  2. Click on the pencil icon under the RobotEyes dashboard:
  1. Click on the orange pencil icon
  2. Change the tile from RobotEyes to RobotControl:
  1. Click on the orange check to accept the changes
  2. Exit out of the side dialog

Now let's control an LED on T.A.R.A.S from our ThingsBoard dashboard.

Adding a switch to our dashboard

In order to control an LED, we need to create a switch:

  1. Click on the RobotControl dashboard
  2. Click on the orange pencil icon
  3. Click...
