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.
Specification:
Product model: KY-040
Working voltage: 5V
One round number of pulse: 20
Diameter of knob cap: 15mm/0.59in
Height of knob cap: 16.5mm/ 0.65in
Widely Applications:
The KY-040 rotary encoder 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.
-Compatible with Arduino/Raspberry Pi controller board.
Package List:
6 * KY-040 360 degree rotary encoder(knob, nut, washer included)
