Summary
In this chapter, you have learned about measuring distance traveled using encoders, including the different types of encoders.
You saw the output that quadrature encoders create and how to interpret this as a turning direction.
You were introduced to the powerful PIO state machines present within Pico and saw how you can give tasks such as handling encoders to them.
You brought this together to create a reusable handler for the encoders, and we had a demonstration to see them working.
In the next chapter, we will plan and buy more devices for our robot, leading to more sensing, and remotely drive it.
