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

A brief history of the Raspberry Pi


First released in 2012, the firstRaspberryPi featured a 700 MHz single core processor and 256 MB of RAM. The Raspberry Pi 2 was released in February of 2015 with a 900 MHz quad core processor and 1 GB of RAM. Released in February of 2016, the Raspberry Pi 3 increased the processor speed to 1.2 GHz. This model was also the first one to include wireless LAN and Bluetooth.

Here is an image of a Raspberry Pi 3 B (2015):

This version of the Raspberry Pi features the following parts:

  • Four USB 2 ports
  • A LAN port
  • A 3.5 mm composite video and audio jack
  • An HDMI port for video and audio
  • An OTG USB port (which we will use to connect the power)
  • A microSD slot (to hold our operating system)
  • A DSI display port for the Raspberry Pi touchscreen
  • A General Purpose Input Output (GPIO) pins
  • A camera port for a special Raspberry Pi camera

The Raspberry Pi Zero was released in November of 2015. Here is an image of it:

Although not as powerful as the previous Raspberry Pis, the Zero featured...
