Example sentences
  • The controller reads the setting of the accelerator pedal from the potentiometers and regulates the power accordingly.
  • Other evaluation tools include surface electromyography, accelerometers, potentiometers, handwriting tremor analysis, and long-term tremor records.
  • Install potentiometers, hook them to the accelerator pedal and connect to the controller.
2A variable resistor with a third adjustable terminal. The potential at the third terminal can be adjusted to give any fraction of the potential across the ends of the resistor.
Example sentences
  • There are no switches, jumpers or potentiometers to set.
  • Therefore I mounted on the axis of the potentiometer, a capacitor as a knob, and a small switch next to it.
  • The controller uses two stock joystick potentiometers, plus another potentiometer that measures the draw on a cable that emerges from the body of the controller.
