This incremental rotary encoder combines a push button and a detent dial, perfect for makers needing a reliable, easy-to-integrate user interface knob with superior feel over common EC11 or KY-040 modules.
A rotary encoder knob is a versatile input device that measures rotation instead of position, unlike a traditional potentiometer. Unlike pots that wear out over time due to physical contact and have limited rotation (usually about 270°), this rotary encoder provides infinite 360° rotation without wear, making it ideal for long-lasting applications. It generates precise digital signals via its incremental quadrature output, perfect for detecting direction and speed of turns.
This makes rotary encoders the go-to choice for modern user interfaces, especially where repeated, reliable input is needed—such as in volume controls, menu navigation, or custom mechanical keyboards. Thanks to its push-button switch integrated into the knob, you get added functionality like selection or confirmation in compact designs.
If you’re looking for a user-friendly, durable alternative to common devices like the EC11 rotary encoder or KY-040 module with knob, this encoder combines smooth operation with rugged performance to handle constant use without degradation. For advanced projects, check out related options like the absolute rotary encoder to explore even more precise control alternatives.
This rotary encoder knob is designed with the future in mind, giving you a reliable, smooth, and tactile input solution for a wide range of DIY or commercial applications.

Here’s a quick wiring overview:
To get you started fast, here’s a simple code snippet for Arduino that reads rotation direction and button presses, allowing easy integration into your project’s user interface:
#define pinA 2
#define pinB 3
#define pinSW 4
volatile int encoderPos = 0;
int lastEncoded = 0;
void setup() {
pinMode(pinA, INPUT_PULLUP);
pinMode(pinB, INPUT_PULLUP);
pinMode(pinSW, INPUT_PULLUP);
attachInterrupt(digitalPinToInterrupt(pinA), updateEncoder, CHANGE);
attachInterrupt(digitalPinToInterrupt(pinB), updateEncoder, CHANGE);
Serial.begin(9600);
}
void loop() {
if (digitalRead(pinSW) == LOW) {
Serial.println(“Button Pressed”);
delay(200); // simple debounce
}
Serial.print(“Position: “);
Serial.println(encoderPos);
delay(100);
}
void updateEncoder() {
int MSB = digitalRead(pinA);
int LSB = digitalRead(pinB);
int encoded = (MSB << 1) | LSB;
int sum = (lastEncoded << 2) | encoded;
| if (sum == 0b1101 | sum == 0b0100 | sum == 0b0010 | sum == 0b1011) encoderPos++; | |||
|---|---|---|---|---|---|---|
| if (sum == 0b1110 | sum == 0b0111 | sum == 0b0001 | sum == 0b1000) encoderPos–; |
lastEncoded = encoded;

| Question | Answer |
|---|---|
| What’s the difference from a potentiometer? | Rotary encoder knobs offer infinite rotation with no wear since they use quadrature pulses, unlike potentiometers that have fixed rotation limits and can wear out over time. |
| How to debounce the rotary encoder? | Most rotary encoder knobs have a debounce-optimized design, but adding a small software debounce (5-10 ms delay) or using hardware filters ensures clean signals for microcontrollers. |
| What is the shaft size? | This encoder features a 6mm D-shaped shaft, standard for most panel-mount knobs and compatible with common mechanical keyboard or Arduino project knobs. |
| How to wire the push button switch? | The built-in momentary push button is a normally open (NO) switch. Connect the SW pin to ground and detect button presses by monitoring this pin for a LOW signal in your code. |
