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

Project overview


In this chapter, we will build a Bluetooth-enabled doorbell using our Raspberry Pi and an Android phone or tablet. We will use an app on our Android phone or tablet, called Blue Dot, which is designed to work with Raspberry Pi projects.

We will start off by looking at RGB LEDs, wherein we will write a small program to cycle through these three colors. We will then create an alarm using a RGB LED and an active buzzer. We will test out the alarm with Python code.

We will write Python code to read button information from Blue Dot. We will then incorporate the code from both the alarm and Blue Dot to create a Bluetooth doorbell system.

The projects in this chapter should take a morning or afternoon to complete.
