Internet of Things with Python

By: Gaston C. Hillar

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.

Understanding LCD displays and their connection types


Sometimes, our IoT device has to provide information to the user with any device connected to an Intel Galileo Gen 2 board. We can use different kinds of electronic components, shields, or breakout boards to achieve this goal.

For example, we can use simple LEDs to provide information that we can represent with colors. For example, a red LED that turns on can indicate that our temperature sensor connected to the board has detected that the ambient temperature is higher than 80 degrees Fahrenheit (ºF) or 26.66 degrees Celsius (ºC). A blue LED that turns on can indicate that our temperature sensor had detected that the ambient temperature is lower than 40 degrees Fahrenheit (ºF) or 4.44 degrees Celsius (ºC). A red LED turned on can indicate that the temperature is between these two values. These three LEDs allow us to provide valuable information to the user.

We can also achieve the same goal using a single RGB LED and work with pulse width...
