Main sections in this model are
3.1. Display section
3.2. Keyboard, indicator & Beeper section
3.3. Lift & motor section
3.4. Sensor section
3.5. LCD section
Program is written using 8051 microcontroller. Two 8255 IC’s are connected to 8051. All circuits are interfaced with 8255. Block diagram of this project is shown below.

3.1. Display section
This section displays the floor number along with the number of cars which has been already parked in that particular floor. So whenever a car is ready to either come down or go up, the program either decrements the count or increments the count automatically according to the going up or coming down of a car. Display section is done by interfacing with 8255(PPI) of 8051.Here 3 ports of 8255 are connected to three 7-segment display. Block diagram of this section is shown.

3.2. Keyboard, indicator & beeper
In this section,12 switches are connected in matrix form and it has three LED’s , RED, GREEN&YELLOW. The person, needed to enter the password has to wait until the GREEN LED glows and when it glows, he has to press the “START” button first. This time the RED LED glows. Then the person has to enter the password. As soon as it is entered, the program checks it with the already stored passwords. If it is correct, YELLOW LED glows. If the entered password is wrong, beeper starts beeping signifying the incorrectness of the password entered. Circuit diagram of keyboard is shown bellow.

The indicator section contains 2 LED’s , RED & GREEN which are present in all the floors. RED LED signifies that the lift is presently busy and shall not entertain any car to enter but if GREEN LED glows, it suggests that the lift is ready and the car can enter the particular floor. Beeper and LED’s are connected to port C upper of 8255.
One more advantage of beeper is that; when a person tries to enter the lift irrespective of finding the display section to be FFF (means the floors are already filled), program sends a signal to Beeper section and it starts beeping indicating that he is not supposed to enter the lift since all the floors are already filled.
sir
i am doing this project .can you mail the pcb layout of this project with all inter connection and its complete circuit diagram.
sir,it will help me more,plz mail me as soon as possible.
sory sir, my email id is ajaykumar110126@gmail.com
Im interested in this project could u plizzz send me the full schematic,circuit diagram and coding or flow chart plizzzzz its urgent
can you plz mail me the details of this project with circuit diagram…i want to make this on as my major project,plz mail me as soon as possible
sir,can u plz send me project report along with ppt of this project
sir can you please send me the circuit diagram of this project. it will be very helpful for us.
thank u in advance…..
Sir, Im interested in this project could u plz mail me the complete circuit diagram of the project?
Plz send me full circuit diagram plz I do this project in final year. Plz help me sir. & all students
Sir, I am a B.E. student and I want to do this project as my final yr project. So i want the complete ckt diagram of this project. I request you to please send me at my email address as early as possible.
Dear sir ,
i’m very interested on this project , can you send me the full details of this nice project ?
Very appreciate 🙂
dear sir, I am also intersted in doing this project, bt i hv ltl confusion, that when a car comes near to ground floor then wheather the user is inside or not, also if at any floor there are 2 cars alerady parked and next car has to be park then how the car will go from lift to that perticular space. Again if when any user wants to go and needs his car back then how his car will get back to perticular person. According to this project it is applicable only for the single car.
sir i m doing this project….need your assistance..contact plz
SIR,
I am the student of B E final yr , in intrested your project . but i have some problem in this project, so please send me circute dig and flow chart, coding please sir its urgant, please send as soon as possible.
Thanks a lot.
I am sty diploma final year sir this project all detills hear. but circuit diagram not pll help me…… pll Response me
sir , i m final year student and i want to make multilevel car parking system as my minor project but i have some difficulty in programing pllzz help me..
plz send me the complete source code in hex file and assembly of this project…………
How we know that parking space is available or not I.e if in each floor their is capacity of park 10 car then how we know that 10 cars are parked or not??
