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

Setting up the circuit


The Pibrella HAT gave us a simple way of programming the GPIO, however, the ultimate goal of Raspberry Pi projects is to create a customized working circuit. We will now take the steps to design our circuit, and then create the circuit using a breadboard.

The first step is to design our circuit on the computer.

Fritzing

Fritzing is a free circuit design software available for Windows, macOS, and Linux. There is a version in the Raspberry Pi store that we will install on our Raspberry Pi:

  1. From the Application Menu, choose Preferences | Add / Remove Software. In the Search box, type in Fritzing:
  1. Select all three boxes and click on Apply, and then OK. After installation, you should be able to load Fritzing from Application Menu | Programming | Fritzing.
  2. Click on the Breadboard tab to access the breadboard design screen. A full size breadboard dominates the middle of the screen. We will make it smaller as our circuit is small and simple.
  1. Click on the breadboard. In the Inspector...
