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.

Working with USB attached storage


Log files that record events related to sensors can grow really fast, and therefore, storing log files in the the microSD storage space might become a problem. We can work with microSD cards up to 32 GB. Thus, one option is to create the Yocto Linux image on a bigger microSD card and continue working with a single storage. This would require us to expand the partition from the default image. The other option is to take advantage of the cloud and just keep a constrained log in our local storage. However, we will work with this option later. Now, we want to explore the additional options we have to use local storage.

As we learned in Chapter 1, Understanding and Setting up the Base IoT Hardware, The Intel Galileo Gen 2 board provides a USB 2.0 host connector, labeled USB HOST. We can use this connector to plug a USB thumb drive for additional storage and save the log file in this new storage.

Before you plug any USB thumb drive, run the following command in...
