  • 360 Degrees Rotary Encoder Module
  • The KY-040 rotary encoder is a rotary input device (as in knob) that provides an indication of how much the knob has been rotated AND what direction it is rotating in. It’s a great device for stepper and servo motor control.  You could also use it to control devices like digital potentiometers.
