Internet of Things with Python

Overview of this book

Internet of Things (IoT) is revolutionizing the way devices/things interact with each other. And when you have IoT with Python on your side, you'll be able to build interactive objects and design them. This book lets you stay at the forefront of cutting-edge research on IoT. We'll open up the possibilities using tools that enable you to interact with the world, such as Intel Galileo Gen 2, sensors, and other hardware. You will learn how to read, write, and convert digital values to generate analog output by programming Pulse Width Modulation (PWM) in Python. You will get familiar with the complex communication system included in the board, so you can interact with any shield, actuator, or sensor. Later on, you will not only see how to work with data received from the sensors, but also perform actions by sending them to a specific shield. You'll be able to connect your IoT device to the entire world, by integrating WiFi, Bluetooth, and Internet settings. With everything ready, you will see how to work in real time on your IoT device using the MQTT protocol in python. By the end of the book, you will be able to develop IoT prototypes with Python, libraries, and tools.

Summary


In this chapter, we understood the difference between pull-up and pull-down resistors to wire pushbuttons and read their status with the mraa and wiring-x86 libraries. We understood the difference between reading the pushbutton statuses with polling and working with interrupts and interrupt handlers.

We created consistent code that allowed the user to perform the same actions with either pushbuttons in the breadboard or HTTP request. We combined code that reacts to changes in the statuses of the pushbuttons with a RESTful API built with Tornado Web server. As in the previous chapters, we took advantage of Python's object-oriented features and we created classes to encapsulate pushbuttons and the necessary configurations with the mraa and wiring-x86 libraries. Our code is easy to read and understand and we can easily switch the underlying low-level library.

Now that we were able to read digital inputs in different ways and configurations that made is possible for users to interact with...
