How to Make Car Reverse Parking Alert System at Home

Parking a buggy or a car in a narrow space can be challenging, especially if there are obstacles around. To address this issue, Keary, an Amish person, created a parking alert system using an Arduino-based obstacle detection device. The system is designed to alert the driver when there is an obstacle nearby, making parking safer and more accessible.

Supplies

• Arduino Nano
• Ultrasonic Sensor
• Buzzer Module
• Jumper wires

Step 1: Circuit Diagram

Connect the VCC of the ultrasonic module and buzzer module to the 5V pin of the Arduino Nano. Then, connect the Trig pin of the ultrasonic module to the D12 pin of the Arduino Nano, and connect the Echo pin of the ultrasonic module to the D11 pin of the Arduino Nano. Next, connect the GND of the ultrasonic module and buzzer module to the GND pin of the Arduino Nano. Connect the I/O pin of the buzzer module to the D8 pin of the Arduino Nano. Finally, connect the positive supply from the battery to VIN and the negative supply from the battery to the GND of the Arduino Nano.

Step 2: Uploading Arduino Code

Step 3: Installation in Car

The parking alert system is installed on the back of the buggy or car, facing the rear. The ultrasonic sensor is mounted on a bracket, which is attached to the back of the vehicle. The sensor is positioned to detect obstacles that are within a few feet of the back of the vehicle.

When the driver puts the vehicle in reverse, the Arduino board is activated, and the sensor starts scanning for obstacles. If an obstacle is detected, the buzzer is activated, and it beeps faster as the obstacle gets closer. This provides the driver with an audible warning, allowing them to stop the vehicle before hitting the obstacle.
