Duinotech XC3736 is a rotary encoder module that can be used to track the rotation of a shaft. It has three pins: CLK, DT, and SW. The CLK and DT pins are used to track the rotation of the shaft, while the SW pin is used to detect when the shaft has been pressed.

The XC3736 can be used to control a variety of devices, such as volume controls, menu navigation systems, and even musical instruments. It is a versatile and easy-to-use module that can be used in a variety of applications.

Here are some of the features of the XC3736:

  • Tracks the rotation of a shaft
  • Can be used to control a variety of devices

How Encoders work
For how encoders work, read the associated manual with the product SR1230.
Software implementation
Using encoders on microcontrollers is an easy task. We can use “pin change interrupts”
to let the UNO count and keep track of the turning. (for other devices, look at pin-change
interrupts or events for your chosen controller).
Connect the following:
Rotation Module
Uno Connection
CLK
Pin 3 (for hardware interrupt)
DT
Pin 2 (for hardware interrupt)
SW
Pin 4 (or any input pin)
+
VCC (5V)
-
GND
(Note, for UNO boards, pin change interrupts can only be on pins 2 and 3)
Note: We recommend 100-200nF capacitors connected between A/B lines to C. You will
get unreliable and erratic behaviour without these capacitors.
Connection between the module and the Arduino is suggested below.

Rotary Encoder Module
Each “notch” that you can feel while rotating the encoder corresponds with one whole
phase change. To track this, we can look at just the falling edge of one of the pins, and
check to see if the other pin matches. Try the below code (swap enc_clk and enc_dt if
it’s not quite as expected)
We must use volatile int and digitalPinToInterrupt() in
order to use interrupt functions; if you would like to read more, check
out:
https://www.arduino.cc/reference/en/language/functions/external-
interrupts/attachinterrupt/
#define enc_dt 2
#define enc_clk 3
#define button 4
volatile int encoderValue = 0;
void setup() {
Serial.begin(9600);
pinMode(enc_dt, INPUT_PULLUP);
pinMode(enc_clk, INPUT_PULLUP);
pinMode(button, INPUT);
attachInterrupt(digitalPinToInterrupt(enc_clk), encoder, FALLING);
}
void loop() {
Serial.println(encoderValue);
delay(100);
}
void encoder() {
if (digitalRead(enc_clk) == digitalRead(enc_dt)) {
encoderValue++;
}
else {
encoderValue--;
}
}
