Arduino things detector using LDR

 put this in arduino ide

Connect as per the video

int sensorPin = A0;

int LedPin = 13;

int sensorValue = 0;

void setup() {

  // put your setup code here, to run once:

pinMode(LedPin, OUTPUT);

Serial.begin(9600);

}

void loop() {

  // put your main code here, to run repeatedly:

sensorValue = analogRead(sensorPin);

if(sensorValue>100)

{

  digitalWrite(LedPin,HIGH);

}

else

{

  digitalWrite(LedPin,LOW);

}

Serial.println(sensorValue);

}
