TBD: Lost-Cost Vehicle Park Assistant Tool

Started Jan. 5, 2023

Abstract or project description

Many parking assistant tools are either too pricey or only come with new car models. In addition, many find it difficult to judge the distance from the front of the car to the curb when parking. This project is the perfect solution, as it is a low-cost Arduino car sensor system that will assist in parking. An ultrasonic sensor is placed underneath the center of the front bumper of the car and is connected to an alert system that is on the dashboard of the car. The alert system consists of a RGB LED and a buzzer. This alert system will sound the buzzer when the driver is too close to a parking curb. Additionally, the LED is color coded to inform the driver of the distance from the curb to the car. For example, when parking in a parking spot, it will display different colors as the driver moves closer to the curb. Then, when the driver is an appropriate distance away from the car, the LED will light red and the buzzer will sound, alerting the driver to stop the car. Because the ultrasonic sensor is outside of the car and therefore susceptible to damage, it is covered by a 3D-printed case. This case will have a lid, which will open up and down when a switch is flipped.
