LDR Code when sun is directly over head open coop door, when light is 0, close door.

use this to determine LDR values:

int analogPin = 3;     // potentiometer wiper (middle terminal) connected to analog pin 3                       // outside leads to ground and +5V int val = 0;           // variable to store the value read void setup() {  Serial.begin(9600);          //  setup serial } void loop() {  val = analogRead(analogPin);    // read the input pin  Serial.println(val);             // debug value }

General Idea:

int RaiseDoor(5); // A5

int LowerDoor(6); // A6

boolean doorup = false; //

int dusk = 500 // will adjust once I have some reference numbers

int LDRE = analogRead(1);

int LDRW = analogRead(0);

void setup()

{

pinMode(RaiseDoor, OUTPUT);

pinMode(LowerDoor, OUTPUT);

}

void Loop() //check door

{

if (LDRE == LDRW && doorup == false);

{

digitalWrite(RaiseDoor, HIGH);

delay(10000);

doorup = true;

digitalWrite(RaiseDoor, LOW);

}

 else if (LDRW > dusk && doorup == true);

{

digitalWrite(lowerdoor, HIGH);

delay10;

doorup = false;

digitalWrite(lowerdoor, LOW);

}

}

CODE:

int LDRW = 0;                                //analog pin to which LDR is connected, here we set it to 0 so it means A0

int LDRE = 1;

int LDRValue = 0;               //that’s a variable to store LDR values

int light_sensitivity = 500;  //This is the approx value of light surrounding your LDR

void setup()

 {

   Serial.begin(9600);            //start the serial monitor with 9600 buad

   pinMode(13, OUTPUT);     //we mostly use13 because there is already a built in yellow LED in arduino which shows output when 13 pin is enabled

 }

void loop()

 {

   LDRValue = analogRead(LDR);          //reads the ldr’s value through LDR which we have set to Analog input 0 “A0″

   Serial.println(LDRValue);                  //prints the LDR values to serial monitor

   delay(50);                                                //This is the speed by which LDR sends value to arduino

   if (LDRValue < light_sensitivity)

     {

       digitalWrite(13, HIGH);

     }

   else

     {

       digitalWrite(13, LOW);

     }

 }
