As we can see, building a security application with the Raspberry Pi is pretty easy. Although we our viewing our dashboard and hosting our sensors on the same Raspberry Pi, it is not too difficult to set up the Raspberry Pi to serve up the dashboard to other computers in your network (or even the internet). In Chapter 10, Publishing to Web Services, we will take our interaction with
sensory data a step further and publish it to the internet.

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.
