SL.No	function
1.	The door has to open automatic when a person or a car gets inside
2.	Whenever the door opens there should be a signal or indicator of sound or a noise

2.6 Concept Generation

concept 1

In the above concept we are making an automatic door open and close system. Here we are using the servo motor which is connected to the door were it helps to open door and close automatically. we are using IR sensor which is used as motion sensor which gives indication to open and close door ,and we are also using arduino which is use to upload coding to the physical board and IR sensor and servo motor both are connected to the aurdino board. arduino board is connected to bread board.

concept 2

In the above diagram we have done a automatic door open and close system, Here we have used PIR sensor which is used for opening and closing of door which is connected to breadboard along with two servo motors and the arduino which is used to upload coding.

concept 3

In the above concept we are making an automatic door open and close system. Here we are using the servo motor which is connected to the door were it i use in mechanism and helps to open door and close door automatically. and we are using the IR sensor which is attached near door handle which is used as motion sensor which gives indication to open and close door ,and we are also using arduino which is use to upload computer code to the physical board where it gives commands and ir sensor is connected to arduino and servo motor also connected to the aurdino board. and connections are done by uing breadboard .were are using breadboard because we can make more connections in board.

concept 4

In the above concept we are making an automatic door open and close system. Here we are using the servo motor which is connected to the door were it helps to open door and close automatically. we are using IR sensor which is used as motion sensor which gives indication to open and close door ,and we are also using arduino which is use to upload coding to the physical board and IR sensor and dc motor both are connected to the aurdino board. arduino board is connected to bread board.
