The KY-040 Rotary Encoder module is a versatile and easy to use device that can use in a variety of projects. It is a great way to add user input to your Arduino projects.

Rotary Encoder Module KY-040 is a rotary input device (as in knob) that provides an indication of how much the knob rotates and what direction it is rotating in. It’s a great device for stepper and servo motor control. You can also use it to control devices like digital potentiometers.

KY-040 Rotary Encoder Module is a small, inexpensive device that can use to measure the rotation of a knob or shaft. It has two outputs that are used to indicate the direction and number of rotations of the knob. The module is compatible with Arduino and other microcontrollers.

This is a low-cost quadrature encoder mount on a circuit board with accessible pins for breadboarding or attaching wires. The encoder outputs pulses on two pins for direction and counts.

KY-040 rotary encoder is a device that generates an electrical signal based upon how much the rotary input device (knob) rotated and the direction it is rotating in. It is a position sensor with a knob and can use to control stepper or servo motors with precision.

A rotary encoder is a type of electromechanical position sensor that can use to identify the angular position of the rotary shaft. This type of sensor or module generates an electrical signal based on the movement and direction of the rotary shaft.

A rotary encoder has a fixed number of positions per revolution. These positions easily feel as small “clicks” you turn the encoder. The KY-040 module has thirty of these positions. On one side of the switch there are three pins.

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

Smooth-action, low-friction movement for easy turning

Breadboard-friendly 5-pin SIP header

KY-040 Rotary Encoder Specifications : –

They normally referres to as A, B and C. In the case of the KY-040, they are oriented as shown. Inside the encoder there are two switches. Once switch connects pin A to pin C and the other switch connects pin B to C. In each encoder position, both switches are either opened or closed. Each click causes these switches to change states as follows:

If both switches are closed, turning the encoder either clockwise or counterclockwise one position will cause both switches to open

If both switches are open, turning the encoder either clockwise or counterclockwise one position will cause both switches to close

Operating Voltage: 5V
Mechanical angle: 360 Degrees
Output: 2-bit gray code
Positions per revolution: 30
