Laser Receiver Sensor - Non-modulator

Here's a step-by-step tutorial on how to connect a Laser Receiver Sensor (Non-modulator) to an Arduino:

Step 1: Gather the Required Equipment:

• Arduino board (such as Arduino Uno)
• Laser Receiver Sensor (Non-modulator)
• Breadboard
• Jumper wires

Step 2: Understand the Laser Receiver Sensor:

• The Laser Receiver Sensor is a non-modulating type of sensor that can be used to detect the presence of laser light.
• It usually has three pins: VCC (power supply), GND (ground), and OUT (output signal).
• The VCC pin is used to provide power to the sensor (typically 5V).
• The GND pin is connected to the ground of the Arduino.
• The OUT pin is the output signal that goes HIGH when the sensor detects the laser light and LOW when it does not.

Step 3: Connect the Laser Receiver Sensor to the Breadboard:

• Insert the Laser Receiver Sensor into the breadboard so that its pins are on separate rows.
• Connect the VCC pin of the Laser Receiver Sensor to the 5V pin on the Arduino board using a jumper wire.
• Connect the GND pin of the Laser Receiver Sensor to the GND pin on the Arduino board using a jumper wire.
• Connect the OUT pin of the Laser Receiver Sensor to any digital pin on the Arduino board, such as D2, using a jumper wire.

Step 4: Read the Laser Receiver Sensor Output:

• Open the Arduino IDE software on your computer and create a new sketch.
• Copy and paste the following code into the sketch:

#define LASER_PIN 2   // Pin number to which the Laser Receiver Sensor output is connected

void setup() {
  Serial.begin(9600); // Start serial communication
  pinMode(LASER_PIN, INPUT); // Set the Laser Receiver Sensor pin as input
}

void loop() {
  // Read the Laser Receiver Sensor output
  int laserValue = digitalRead(LASER_PIN);
  
  // Print the output value to the serial monitor
  Serial.print("Laser Detected: ");
  Serial.println(laserValue);
  
  delay(500); // Add a delay for stability
}

• Verify and upload the code to your Arduino board.
• Open the Serial Monitor in the Arduino IDE to view the output of the Laser Receiver Sensor.
• Observe the output changing in the serial monitor as the Laser Receiver Sensor detects or does not detect the laser light.

That's it! You have successfully connected a Laser Receiver Sensor (Non-modulator) to an Arduino and read its output. You can now use the output of the sensor in your Arduino project for various applications such as laser beam sensing, object detection, and more.
