The objective of this project is to control the status of a door with the use of two buttons.
By using an ultrasonic sensor, is possible to detect a person that is close to the door. A blue LED will indicate when someone is at the door. With the use of the buttons, you can open and close the door.
A red LED will indicate when the door is closed, and a green LED will turn on when is open.
The LCD screen will show the status of the door with text.
