Internet of Things Programming Projects

Overview of this book

The Internet of Things (IOT) has managed to attract the attention of researchers and tech enthusiasts, since it powerfully combines classical networks with instruments and devices. In Internet of Things Programming Projects, we unleash the power of Raspberry Pi and Python to create engaging projects. In the first part of the book, you’ll be introduced to the Raspberry Pi, learn how to set it up, and then jump right into Python programming. Then, you’ll dive into real-world computing by creating a“Hello World” app using flash LEDs. As you make your way through the chapters, you’ll go back to an age when analog needle meters ruled the world of data display. You’ll learn to retrieve weather data from a web service and display it on an analog needle meter, and build a home security system using the Raspberry Pi. The next project has a modern twist, where we employ the Raspberry Pi to send a signal to a web service that will send you a text when someone is at the door. In the final project, you take what you've learned from the previous two projects and create an IoT robot car that you can use to monitor what your pets are up to when you are away. By the end of this book, you will be well versed in almost every possible way to make your IoT projects stand out.

Summary

In this project, we used the power of the Raspberry Pi to create an IoT analog weather dashboard. In this case, this involved an internet-controlled servo used as an analog meter. It's not too hard to imagine how we may alter our code to display data other than weather data. Picture an analog meter displaying the tank level from a distant factory, where the level data is communicated over the internet.

The intuitive nature of analog meters makes them perfect for applications where a glance of the data is all that is required. Combining analog meters with data from the internet creates a whole new world of data display.

In Chapter 7, Setting Up a Raspberry Pi Web Server, we will take a step away from the analog world and explore how we may use the Raspberry Pi as a web server and build a web based dashboard.
