Ky-040 Rotary Encoder Sensor Module With Push Button Arduino printer The thermistors are in theKY 040 Rotary Encoder Sensor Module Brick Sensor is a rotary input device (as in knob) that provides an indication of how much the knob has been rotated AND what direction it is rotating in. Its a great device for stepper and servo motor control. You could also use it to control devices like digital potentiometers. M274 360 rotary Degree encoder, is an incremental electro mechanical device that converts the angular position or motion of a shaft or
