WISDUM KY-040 Rotary Encoder Module 360 Degree Switch Encoders with Knob Cap Brick Sensor Modules (Pack of 6pcs)

KY-040 Rotary Encoder Module -The rotary encoder can count the number of pulse output during rotation in the positive direction and reverse direction through the rotation and this rotation counts are not limited. -With the key on the rotary encoder, you can reset to the initial state, that is, counting from
0.
