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 worked with Tornado web server, Python, the HTTPie command-line HTTP client, and the mraa and wiring-x86 libraries. As in the previous chapters, we took advantage of Python's object-oriented features and we generated many versions of RESTful APIs that allowed us to interact with the board in computers and devices connected to the LAN.

We could compose and send HTTP requests that printed number in LEDs, changed the brightness levels for three LEDs and generated millions of colors with an RGB LED.

Now that we created our first RESTful APIs that made is possible for computers and devices to interact with our IoT device, we can take advantage of additional features that allow us to read digital inputs and analog values, which is the topic of the next chapter.
