Detailed Working of DIY Arduino System for Car Parking with IR Sensor and Step-by-Step Instructions:

The DIY Arduino System for Car Parking with IR Sensor is a sophisticated yet easily understandable application of embedded systems designed to streamline the car parking process. The core of this system is an Arduino microcontroller that interprets signals from different sensors and controls various output devices to manage car parking slots efficiently.

The journey begins with a transformer that steps down the 220V AC mains voltage to a more manageable 24V AC. This 24V is then fed into two voltage regulators, the LM7812 and LM7805. The LM7812 converts the 24V AC to 12V DC, while the LM7805 further reduces this 12V to 5V DC for the Arduino microcontroller and other components requiring lower voltage.

At the heart of the system lies the Arduino Nano, orchestrating the data flow and control mechanisms. Connected to the Arduino is an LCD screen that provides real-time updates and status messages about the parking slots. The Arduino receives power from the 5V regulated output, ensuring smooth operation.

The car parking system leverages multiple IR sensors to monitor the occupancy status of parking slots. These sensors, labeled as SENSOR FOR SLOT-1, SLOT-2, SLOT-3, and SLOT-4, are strategically placed to detect the presence of a car in the respective slot. The sensors convert the detected presence into an electrical signal, which is then relayed to the Arduino for processing.

When a car approaches the entry gate, a dedicated IR sensor detects its presence. This sensor, connected to the Arduino, triggers the servo motor that controls the gate mechanism. The servo motor receives commands from the Arduino to either open or close the gate, providing a seamless entry for the vehicle. The gate motor operates using the same 5V power supply, ensuring synchronized activity.

Once the car enters, the relevant IR sensor detects the presence of the car in a particular slot. This data is immediately sent to the Arduino, which then updates the status on the LCD screen, indicating that the slot is now occupied. The system continuously monitors the sensors to update the availability of parking slots in real-time.

In essence, the Arduino microcontroller acts as the brain of the operation, constantly receiving and processing data from the sensors. It interprets this data to control the servo motor and update the LCD screen, making the parking management process almost autonomous. This integration of components ensures that the car parking system is both efficient and user-friendly.

Furthermore, the use of voltage regulators guarantees that all components receive the required voltage levels, preventing any potential damage from voltage fluctuations. The overall design is both robust and scalable, allowing for additional sensors or even more advanced features to be integrated in the future.

To summarize, the DIY Arduino System for Car Parking with IR Sensors is an illustrative example of automated parking management. It showcases the effective use of sensors, microcontrollers, and actuators to create a smart, reliable system. By following the step-by-step instructions and understanding the flow of data, one can replicate or even build upon this project for more advanced applications.

Modules used to make DIY Arduino System for Car Parking with IR Sensor and Step-by-Step Instructions :

1. Power Supply Module

The power supply module is crucial for converting the high voltage from the mains supply (220V) to a lower voltage that the Arduino and sensors can use. In this project, a transformer steps down the 220V AC to 24V AC. This is then rectified using a bridge rectifier to convert AC to DC. After rectification, the voltage is smoothed by a capacitor to ensure stable DC supply. Lastly, voltage regulators (LM7812 and LM7805) are used to provide 12V and 5V DC outputs respectively. The 12V output powers components like the servo motor, while the 5V output powers the Arduino and other low-power sensors.

2. Arduino Control Module

The heart of the car parking system is the Arduino board. It receives inputs from various IR sensors placed at different parking slots and the car entry gate. The Arduino processes these signals to determine the presence of a car in a slot or detect an approaching car at the gate. Based on the sensor data, the Arduino controls the servo motor to open or close the gate and updates the display on the LCD screen. The Arduino is also responsible for running the control logic that manages the parking slots and ensures smooth operation of the overall system.

3. Sensor Module

IR sensors play a pivotal role in the car parking system by detecting the presence of cars. In this project, several IR sensors are used: one at the car entry gate and one at each parking slot (totaling five sensors). Each sensor consists of an IR emitter and receiver. When a car interrupts the IR beam, the sensor detects the presence of the vehicle and sends a signal to the Arduino. The sensor at the entry gate detects incoming cars, signaling the Arduino to open the gate. The sensors at the parking slots check for available or occupied spaces by sensing cars in the respective slots.

4. Servo Motor Module

The servo motor is responsible for physically opening and closing the gate of the parking system. The Arduino controls the servo motor through PWM (Pulse Width Modulation) signals. Upon receiving a signal from the entry gate sensor, the Arduino commands the servo motor to rotate, opening the gate and allowing the car to enter. Once the car has passed, the Arduino sends another signal to the servo motor to close the gate. This automated gate control ensures smooth entry and exit of cars, preventing manual intervention and enhancing security and efficiency of the parking system.

5. LCD Display Module

The LCD display serves as the user interface for the car parking system, providing real-time updates about the status of parking slots. It is connected to the Arduino and displays messages such as the number of available slots, slot occupancy, and entry gate status. The Arduino updates the LCD information based on inputs from the IR sensors. For instance, if a parking slot becomes occupied or vacant, the LCD display shows the updated count of available slots. This visual feedback helps users quickly find an available slot, making parking more efficient and user-friendly.
