This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

An autonomous robot that detects and avoids obstacles using Arduino Uno, Ultrasonic Sensor (HC-SR04), Servo Motor, and L298N Motor Driver. The robot continuously scans its surroundings and makes ...
