Built with an ultrasonic sensor and a servo motor, the system rotates the sensor across set angles, sending out sound pulses and calculating distance based on how long the echoes take to return. As the Arduino processes each angle-and-distance reading, the data is displayed on a screen or computer interface to form a live “radar map.” Obj
