It is always a bit difficult to try new things. If this was your first attempt at programming, you may still feel a bit uncomfortable as I ask you to create or edit files. However, I will try to give you explicit instructions on what to type so that you can be successful. There is one major challenge when working with computers. They always do exactly what you tell them to do, not necessarily what you wanted them to do. So if you encounter problems, check several times to make sure that your code matches the example exactly. Now on to the next chapter and some actual coding! In the next chapter, you'll be building a simple wheeled platform that you can control with the BeagleBone Blue.
