Ultrasonic sensors are used to detect the presence of obstacles, calculate the distance to these obstacles, and relay this information to the driver through visual and auditory cues. This research ...

This project is an autonomous robotic car built using an Arduino microcontroller. The car uses an HC-SR04 ultrasonic sensor for obstacle detection, an L293D motor driver shield to control four DC ...
