Built with an ultrasonic sensor and a servo motor, the system rotates the sensor between specific angles, sends sound waves, and measures distance based on how long the reflected waves take to return. This is how the radar detects the location of objects around it. The Arduino microcontroller processes the sensor data and displays the distance information on a screen or
