Mastering IOT

By: Colin Dow, Perry Lea

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. We’ll begin our journey with an introduction to Raspberry Pi and quickly jump right into Python programming. We’ll learn all concepts through multiple projects, and then reinforce our learnings by creating an IoT robot car. We’ll examine modern sensor systems and focus on what their power and functionality can bring to our system. We’ll also gain insight into cloud and fog architectures, including the OpenFog standards. The Learning Path will conclude by discussing three forms of prevalent attacks and ways to improve the security of our IoT infrastructure. By the end of this Learning Path, we will have traversed the entire spectrum of technologies needed to build a successful IoT system, and will have the confidence to build, secure, and monitor our IoT infrastructure. This Learning Path includes content from the following Packt products: Internet of Things Programming Projects by Colin Dow Internet of Things for Architects by Perry Lea

Chapter 14. Controlling a Servo with Python

Analog meters and instrumentation were the only ways to display data prior to the rise of digital technologies. Once the move was made to digital, analog meters fell out of vogue. Generations that grew up learning to tell the time on an analog clock may suddenly find this skill to be out of date, as digital displays of time have become the norm. 

In this chapter, we will bridge the gap between the digital and analog worlds by changing the position of a servo motor based on a digital value.

The following topics will be covered in this chapter:

  • Wiring up a servo motor to the Raspberry Pi
  • Controlling the servo through the command line
  • Writing a Python program to control the servo
