The KY-010 Photo Interrupter module consists of an optical emitter/detector. If the sensor is broken the LED is turned on.

 

Connection

Connect the power line (middle) and ground (left) to +5V and GND. Connect the signal (S) to pin 3 on the Arduino.

S (right) Pin 3

 

Code

int Led = 13; // define LED pin
int buttonpin = 3; // photo interrupter pin
int val;
 
void setup()
{
	pinMode(Led, OUTPUT); // LED pin as output
	pinMode(buttonpin, INPUT); //photo interrupter pin as input
}
 
void loop()
{
	val=digitalRead(buttonpin); //read the value of the sensor 
	if(val == HIGH) // turn on LED when sensor is blocked 
	{
		digitalWrite(Led,HIGH);
	}
	else
	{
		digitalWrite(Led,LOW);
	}
}
