Summary
In this chapter, you learned what a PWM signal is and how it can be easily generated using a PWM generator with few Bash commands. We also saw a practical example of how we can manage a servo motor using the sysfs interface that Linux offers to us to do this job.
In the next chapter, we're going to close this book by presenting a list of different kinds of devices that an embedded GNU/Linux developer may encounter in their professional life by explaining how they can easily manage them using our embedded kits.
