This project is related to smart window which can be controlled by mobile phone using android mobile app.

The window is also Smart enough to detect Rain and fast moving air.

Below is the code for arduino to control smart window.

The Code :-

#include 
#include  
 #include  
Servo servo1;
Servo servo2;// create servo objects to control a servo 
                // twelve servo objects can be created on most boards
boolean WindowStatus = 0; // status of window i.e open = 1 and close = 0
boolean DoorStatus = 0; // status of door i.e open = 1 and close = 0
int pos = 0; // variable to store the servo position 
 SoftwareSerial mySerial(9, 10);
void setup() 
{ 
 mySerial.begin(9600); // Setting the baud rate of DOOR controller
 Serial.begin(9600); // Setting the baud rate of Switch board controller
 servo1.attach(5); // attaches the servo on pin 5 to the servo object 
 servo2.attach(6); // attaches the servo on pin 6 to the servo object 
 pinMode(13, INPUT_PULLUP); // switch to open/close window
 WindowStatus=EEPROM.read(0);
 pinMode(A0, INPUT_PULLUP);
  pinMode(2, INPUT_PULLUP);
  pinMode(3, INPUT_PULLUP);
  pinMode(4, INPUT_PULLUP);
