int sensorPin = A0; // select the input pin for ldr
int sensorValue = 0; // variable to store the value coming from the sensor
void setup() {
Serial.begin(9600); //sets serial port for communication
}
void loop() {
sensorValue = analogRead(sensorPin); // read the value from the sensor
Serial.println(sensorValue); //prints the values coming from the sensor on the screen
delay(300);
}

OUTPUT:

After Upload Code to Arduino Click on Tools->Serial Monitor to see the Value or you can Also see it’s Graph by Clicking Tools->Serial Plotter
