Open the Arduino software and paste the Arduino code (the text in the box near the bottom of the post) into a new sketch. Click Sketch > Verify / Compile to make sure the code is properly in there.

I can’t possibly hack the entire Arduino code but using the Sparkfun code provides a manageable subset for experimenting. For this article we’ll just look at the controlling the motors.

Having easily parsed code reduces your cognitive load and makes solving problems easier. To try and help with this, [PTS93] developed the Stator library to make certain common tasks simpler to read.
