By rotating the rotary encoder can be counted in the positive directionand the reverse direction during rotation of the output pulsefrequency, unlike rotary potentiometer count, this rotation counts arenot limited.
With the buttons on the rotary encoder can be reset to its initialstate, that starts counting from 0.
