In this project we automated household appliances and we used a Arduino, Bluetooth Module, wires and sensors. We know that it is already made but we want to make it.

We can make a programme that controls the power of the whole house. We can make an app that consists of multiple buttons for every room and every electronic device in the room. The room will consist multiple sensors and screens that will tell the person the temperature of the room and the number of lights on in his house or room.We will first make and programme the app.(using Mit app inventor 2)We will then make the hardware including sensors, Arduino, Temperature Sensor, nails, drill and BlueTooth Module.Then we will programme the hardware. We will fit the led Screen and the rest of the hardware in a metal or wooden box or on the wall.The box will have the A hole on one side for the lock to come out. Bluetooth will open and close the lock from the app and the app will also tell us the temperature.

  • Adding DHT Sensor

    Shaherayar Khan10/27/2018 at 06:39 0 comments

    Today we added a DHT sensor to our project and DHT measures the temperature and humidity of outside atmosphere and tells us on the app what the temperature and the humidity is  outside. We had some problems adding it so we looked up some websites and then we fixed the problem and the problem was we couldn't receive the values from the DHT sensor, so as i said we visited some websites and then we solved the problem it took us some time but we fixed it and the project is almost done.

    The Code is:

    #include <dht.h>

    #define dht_apin A0

    dht DHT;

    #include <SoftwareSerial.h>

    SoftwareSerial BT(10,11); // RX, TX

    int vib_pin=2;

    int led_pin=13;

    int led = 8;                     

    int val = 0;                               

    void setup() {






     pinMode(led, OUTPUT);   


    void loop() {

     int s;

     int inByte = 0;

     int motion = digitalRead(7);

      val = digitalRead(motion);   

     if (val == HIGH) {           

       digitalWrite(led, HIGH);  



     else {

         digitalWrite(led, LOW);





       Serial.print("Current humidity = ");


       Serial.print("%  ");

       Serial.print("temperature = ");


       Serial.println("C  ");




     if (BT.available()){

       inByte =;

       if(inByte == 'S'){




        if(inByte == 'X'){

  • Automatic Door Opener for disabled people

    Shaherayar Khan06/02/2018 at 07:26 0 comments

    There will be sensors used to open the door and we are still working how close the door. We will use app to open the door or use the sensor to open the door. This will make it easy for disabled people to open the door. 

  • Future additions coming soon

    Shaherayar Khan05/26/2018 at 07:40 0 comments

    We are adding. Automated water dispenser. if a person wants to drink water that he will send the signal using blue tooth module and when he is there the water will be filled in glass. we will even put a sonar sensor so it does not over fill.
