A guide is often produced alongside a physical computing project to document how the project was created.
Different physical computing devices have different features and capabilities.
Choosing the correct device for a project depends on the requirements of the project.

There is no point in doing an evaluation once a project is finished as you are not going to go back and make any more changes.

Evaluations help learning by understanding your creative process and finding ways to improve. This often informs projects that you do in the future.

Prototype - an early model of a program or digital system
Device - a physical machine that can perform computations and process information electronically
