Example 08‐Motor toggles between Limit‐Switches - GSTCH/SketchMadeEASY GitHub Wiki

Motor with variable speed, toggles between two limit switches.

Sketch Made EASY supports controlling motors by different chips (shields):

The different variants are presented in the following chapters. The difference is in the definition of the actuator. If Sketch Made EASY is installed, it can be opened via menu: "File:/Example/SketchMadeEASY/Examples/08-MotorTogglesBetweenLimitSwitches".
