👉 Stepper is a mechanical device that moves an object or a series of objects by means of a series of moving parts known as "steps." These steps are typically made up of smaller units called "stages" and may be arranged in any pattern to create a desired motion or movement. The term "stepper" refers to the physical mechanism used for controlling such devices, which can include various types of motors, valves, sensors, and other components that control the movement of the device.
