Internet of Things Programming Projects: Build modern IoT solutions with the Raspberry Pi 3 and Python
The Internet of Things (IoT) has managed to draw the attention of researchers and tech enthusiasts since it effectively combines traditional networks with instruments and devices.
In the Internet of Things Programming Projects, we unleash the power of Raspberry Pi and its programming language Python to build winning projects. The first part of the book introduces the Raspberry Pi, and the reader learns how to set it up, and then jump right into Python programming. Then, the reader dives into real-world computing by creating a simple “Hello World” application utilizing flashing LEDs.
As you make your way through the chapters, you go back to an age when analog needle meters governed the world of data display. You learn how to retrieve weather data from a web service and present it on an analog meter, and build a home security system using the Raspberry Pi. Another project comes with a modern twist, where we employ the Raspberry Pi to send a signal to a web service that transmits a text when someone is at the door. In the final project, you take what you have discovered in the preceding two projects and create an IoT robot car that you can use to observe what is happening when you are away from home.
By the end of this book, the reader is quite skilled in virtually every possible way to make an IoT project stand out.
