Now, this sketch is quite a bit longer than some of other code

examples, and there is a lot going on here. Unfortunately, as your

methods of input become more advanced, the software needed to

read its data can become more complicated. With that, let’s break

down what we have written and discuss how we might be able to

use this data to control the motors in our robotic-arm design.

One of the first things we need to do in our code is create the

variables we require to read the data from our rotary encoder.

First, we establish a CLK (clock) ...
