KY-040 189 degree Rotary Decoder Encoder Module for Arduino AVR PIC

Description:–

A 189 Degree Rotary Encoder is a Bread Board Friendly extremely precise module that provides an indication of how much the knob has been rotated AND what direction it is rotating in. It is an incremental electro-mechanical device that converts the angular position or motion of a shaft or axle to digital code. The output of incremental encoders provides information about the motion of the shaft, which is typically further processed in processor / controllers into information such as speed, distance, and position.

It’s a great device for stepper and servo motor control.  You could also use it to control devices like digital potentiometers.

Features:- 

• Incremental Encoder
• Built-in 10k resistor
• Incremental Encoder
• Supply Voltage: 3-5V
• Left/Right rotary output pulse, each circle with 20 pulse
• Cycles per revolution (CPR): 20

Rotary Encoder Rotary Encoder Module is an incremental electro-mechanical device that converts the angular position or motion of a shaft or axle to digital code. The output of incremental encoders provides information about the motion of the shaft, which is typically further processed in processor/controllers into information such as speed, distance, and position. The buttons on the rotary encoder can be reset to their initial state, which starts counting from 0.
