3.Example
This is a simple sketch that shows how to count the encoder position and how to determine
direction of rotation. It has no switch debounce, nor does it use interrupts. A fully developed
application might need to incorporate these in order to make it robust.
******Code Begin******
int pinA = 3; // Connected to CLK
int pinB = 4; // Connected to DT
int encoderPosCount = 0;
