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

Introducing Blue Dot


Blue Dot is an Android app available in the Google Play Store. It works as a Bluetooth remote for the Raspberry Pi. When loaded into your Android phone or tablet, it is basically a big blue dot that you press to send a signal to the Raspberry Pi. The following is a picture of the Blue Dot app loaded onto a tablet:

It may be used as a Bluetooth joystick of sorts, as positional, slider, and rotational data may be sent from the app to your Raspberry Pi, depending on how you interact with the dot on the screen. We will add some of this functionality to our doorbell application by creating custom rings based on how the Blue Dot is pressed. To install Blue Dot on your Android phone or tablet, visit the Google Play Store and search for Blue Dot.
