This project demonstrates a simple Radar System using an Arduino UNO, an ultrasonic sensor (HC-SR04), and a servo motor. It can detect objects within a certain range and beeps when one is found.
- The servo motor rotates the HC-SR04 ultrasonic sensor from left to right.
- The ultrasonic sensor measures distances to detect nearby objects.
- The system continuously scans the area and activates the red LED and buzzer whenever an object is detected.

- Assemble the circuit following the wiring guide.
- Upload the provided Arduino code to your Arduino UNO.
- Once powered on, the servo motor will start scanning the area by moving the ultrasonic sensor from left to right.
- When an object is found, the red LED will light up and the buzzer will beep.
- The radar system continuously updates as it scans for obstacles.
