Project Tutorial

An 8051 microcontroller-based electronics project that demonstrates the creation of an automated car parking system. This project features a multi-floor parking structure with a lift that transports cars to designated parking areas based on the occupancy status of the system. Cardboard sheets can be utilized to construct the building, and toy cars can be used for demonstration purposes. The automatic multi-storied car parking system serves as an effective solution for car parking challenges in modern environments, where space optimization is critical, especially in large companies and apartments. In scenarios requiring parking for over 100 vehicles, this system effectively reduces space wastage by enabling vehicles to be parked floor by floor. The system is developed using the 8051 microcontroller, with programming tailored to this concept. A display unit at the ground floor acts as a counter, indicating the number of cars parked on each floor and whether any floors are fully occupied.

The system features a lift controlled by a stepper motor, equipped with green and red LED indicators on each floor to signal the lift's status. A glowing red LED indicates that the lift is busy, while a green LED signifies that it is ready for operation. The project accommodates three parking floors, with a maximum capacity of ten vehicles per floor, adjustable according to requirements. The third floor is designated for VIPs, who must enter a four-digit password for access. The microcontroller verifies the entered password against a stored list of ten passwords, activating a siren if the input is incorrect.

When a vehicle enters the lift, a light-dependent resistor (LDR) detects its presence, triggering a red LED and signaling the motor to operate. Once the lift reaches the designated floor, the microcontroller checks the occupancy status against the predefined capacity. If the selected floor is full, the lift moves to the next available floor. As soon as a car is parked, the display counter at the ground floor updates to reflect the reduced capacity. After parking, the lift returns to its initial position, and the motor halts, allowing the green LED to illuminate, indicating that the lift is free. For users wishing to return to the ground floor, they need to focus a headlight on the LDR located on their respective floor. This action prompts the sensor to signal the motor to return the lift, activating the red LED to indicate that the lift is occupied. Once the lift arrives at the designated floor, the car enters, and the ground floor display counter decreases accordingly.

Overall, this automated car parking system exemplifies the integration of microcontroller technology with practical applications, providing an innovative solution to contemporary parking challenges while optimizing space utilization effectively.A 8051 microcontroller based electronics project. This demo project explains how to make a car parking system automated. Here, there is a multi floor parking system, and a lift will take your car to the appropriate parking area depending on the cars that are already occupied in the system. Use some cardboard sheets to make the building and take some toy cars to have a demo! Automatic multi-stored car parking systemis very good substitute for car parking area. Since in modern world, where space has become a very big problem and in the era of miniaturization its become a very crucial necessity to avoid the wastage of space in modern, big companies and apartmentsetc. In space where more than 100 cars need to be parked, it`s avery difficult task to do and also to reduce the wastage of area, this system can be used.

This Automatic Car Parking enables the parking of vehicles-floor after floor and thus reducing the space used. Here any number of cars can be park according to requirement. This makes the system modernizedand even a space-saving one. This idea is developed using 8051 Microcontroller. Here program is written according to this idea using 8051. A display is provided at the ground floor which is basically a counter that displays number of cars in each floor.

It informs whether the floors are fully filled with the cars or is it having place in a particular floor or not. There is facility of lift to carry the car to up and down. Movement of Lift is controlled by stepper motor. An indicator with a green and red LED is kept in all the floors to indicate whether the lift is busy or is it ready to take the car up or down.

If the redLED glowsthat means the lift is already engaged and the person has to wait for the green LED to glow. In this project we have provided three floors of a building for car parking. Maximum storage capacity of each floor is given as ten. Storage capacity can be changed according to the requirement. Any one can enter to first or second floor. The third floor in this model is for VIP`s only. Therefore when VIP`s are to be entering they are expected to enter their password and they will be taken to the third reserved floor.

The password will be of 4 digits. The processor checks for the password entered and if it is found to be wrong, a siren is heard. In this particular model 10 passwords are stored. So when a password is entered, the processor checks for it and it is compared with 10 passwords. It indicates whether it is the correct one or not. When the car enters the lift, the LDR detects its presence and sends a signal to glow RED LED indicating that the lift is busy. It also sends a signal to motor which makes the motor to rotate. After RED LED glows the lift will take the person and the car up to the floor where the space for parking is available.

(For VIP it will be the third floor). When the lift reaches the first floor, the processor compares the filled amount to that of the already fed capacity of that floor, and if it finds that the first floor is fully filled, it goes to the second floor and thus the procedure stops here. As soon as a car is placed in a particular floor, the display counter at the ground floor increments as to indicate the floor capacity has decreased by one.

After the lift places the car in a particular floor, it comes back to its normal position and that time, the motor that drives it, also stops. Now processor sends signal to glow GREEN LED indicating that lift is free. When a person needs to come down from a particular floor to ground floor, he is expected to focus the headlight onto the LDR placed in that floor.

Now sensor section sends signal to motor that the lift has to be send back to that particular floor and sends a signal to glow RED LED indicating that the lift is busy. As soon as the lift reaches that particular floor car should come inside the lift, the display counter at the ground floor decrem
