Internet of Things Programming Projects

By: Colin Dow

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.

Controlling the Robot Car with Web Service Calls

One day, driverless cars will dominate our streets and highways. Although the sensory information and control algorithms will be located in the car itself, we will have the ability (and it will possibly be a legislative requirement) to control the cars from elsewhere. Controlling driverless cars will require sensory information from the car to be sent to a control station in the form of speed, GPS location, and so on. Conversely, information from the control station will be sent to the car in the form of traffic and directions.

In this chapter, we will explore both the sending of sensory information from T.A.R.A.S and the receiving of control information by T.A.R.A.S.

The following topics will be covered in this chapter:

  • Reading the robot car's data from the cloud
  • Using a Python program to control a robot car through the cloud...
