The system model shown in Fig. 1 consists of two
floors. However to implement the system in some
environment we can have hundreds of floors due to its
rotational floor to floor switching capability. Each user is
assigned a Floor and Parking lodge number. In the base
section along with few mechanical parts it contains a DC
motor to perform the rotation. Here for simplicity we used
one door only which is simultaneously used for Entrance
and Exit. The processor i.e the Microcontroller is used
with the LCD section and is integrated with the hardware
using switches. The keypad instructs the motor to switch
on the floors. A simple switch is used on the door which
acts as a sensor to detect the weight of the car to open and
close the door
