There are four main types of robot programming icons used in EdWare. These are control icons (red), read icons (blue), data icons (green) and flow icons (yellow).
Throughout this EdBook we will use almost every icon at least once. Some of the more advanced icons, such as the read icons will be covered in future EdBooks. For more information about all of the icons see the EdWare programming manual.
The read and data icons require at least one variable to be added to the program, some icons use different sized variables. More on variables later.
