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.
