1-28. ENCODER test

Contents: Check the rotation response of the
Encoder.
When the Encoder rotates clockwise, the
">" mark on the left side moves to the right.
The ">" mark changes to the "<" mark
when it reaches the right side. Then, when
the Encoder rotates counterclockwise, the
"<" mark moves to the left. When the "<"
mark reaches the left side, the Encoder is
OK.
The Encoder rotates slowly.
