Arduino and LDR module Interfacing

Interfacing Arduino with LDR module to activate servo motor

Circuit: (Arduino with LDR as input and servo motor as output)

Arduino Code:

#include <Servo.h> 

Servo myservo; // create servo object to control a servo 

const int LDRpin = 4;

void setup() { 

   myservo.attach(5); // pin 5 of Arduino with servo motor

   pinMode(LDRpin, INPUT);

   myservo.write(0);

   delay(500);

   myservo.write(90);

}

void loop() { 

  if(digitalRead(LDRpin)==0)

     myservo.write(0); // tell servo to go to a particular angle

  else

    myservo.write(90);

}
