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

Reading our button state using Bluetooth and Python


As mentioned previously, we are able to interact with the Blue Dot app in more ways than just a simple button press. The Blue Dot app can interpret where on the button a user presses, as well as detect double presses and swipes. In the following code, we will read from the Blue Dot app using Python.

Reading button information using Python

Do the following :

  1. Open up Thonny from Application Menu | Programming | Thonny Python IDE
  2. Click on the New icon to create a new file
  3. Type the following into the file:
from bluedot import BlueDot
from signal import pause

class BlueDotButton:

    def swiped(swipe):

        if swipe.up:
            print("Blue Dot Swiped Up")
        elif swipe.down:
            print("Blue Dot Swiped Down")
        elif swipe.left:
            print("Blue Dot Swiped Left")
        elif swipe.right:
            print("Blue Dot Swiped Right")


    def pressed(pos):
        if pos.top:
            print("Blue Dot Pressed from...
