Laser Receiver  Sensor                Arduino UNO
S                                                                       D2
+                                                                       5V
–                                                                        GND

Code:
int LED = 13;
int LaserSensor = 2;
int SensorReading = HIGH;
int Laser = 12;

void setup() {
pinMode(LED, OUTPUT);
pinMode(Laser, OUTPUT);
pinMode(LaserSensor, INPUT);
}

void loop() {
digitalWrite(Laser, HIGH);
delay(200);

SensorReading = digitalRead(LaserSensor);
if(SensorReading == LOW)
{
digitalWrite(LED, HIGH);

}
else
{
digitalWrite(LED, LOW);
}

}

Result:  
When there is an obstacle, the LED will turn on
When there is no obstacle, the LED will turn off
