Project 29: Rotary Encoder

Introduction
The rotary encoder can count the pulse outputting times during the process of its rotation in
positive and reverse direction by rotating. This rotating counting is unlimited, not like potential
counting. It can be restored to initial state to count from 0 with the button on rotary encoder.
