The rotary encoder can count the quantity of output pulse in the positive and negative direction rotation.The rotation counting is unlimited.An incremental encoder is a rotating sensor that converts rotation.
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.
