The functionality of a project is created by adding and wiring functions on the Wiring Diagram using the many functions from the Function Palette shown at the bottom left.

The Wiring Diagram can be opened for each sample project and can serve as a starting point for building new projects.

Without any programming knowledge you can implement a great deal of functionality.

Below is the diagram for the project on the left, which implements a differential equation with two integral functions to model the trajectory of a projectile.
