The slider module can be used to control input.

Working principle

You can slide the slider on the slider module to change the resistance and thus change the voltage in the corresponding circuit. Based on the relation between the voltage and resistance, the resistance can be calculated and thus the position of the slider can be determined.

Real-life examples

  • The sound volume of a cell phone is set through a slider.

  • The progress of video playing is controlled through a slider.
