Pinout 

Arduino Code

The following Arduino example code demonstrates how to read the digital output from the laser sensor module. When a laser is detected on the sensor input pin, an action such as turning on a buzzer or LED is triggered. Serial output is used to monitor the sensor status.

const int SENSOR_PIN = 2;   // Pin 2 for the sensor
const int ACTION_PIN = 3;   // Pin 3 for the action

void setup() {
  Serial.begin(9600);
  Serial.println("Robojax.com Laser Module Test");

  pinMode(SENSOR_PIN, INPUT);
  pinMode(ACTION_PIN, OUTPUT);
}

void loop() {
  int detected = digitalRead(SENSOR_PIN);

  if (detected == HIGH) {
    digitalWrite(ACTION_PIN, HIGH);
    Serial.println("Detected!");
  } else {
    digitalWrite(ACTION_PIN, LOW);
    Serial.println("No laser");
  }

  delay(200);
}
