RADAR SYSTEM USING ULTRA SONIC SENSOR

CIRCUIT DIAGRAM:

To create a simple RADAR system using Arduino UNO, ultrasonic sensor, and servo motor, which scans an area and detects objects in its range. The distance is measured and displayed on the Serial Monitor .

Components Required:
Arduino UNO
HC-SR04 Ultrasonic Sensor
Servo Motor (e.g., SG90)
Breadboard & Jumper Wires

Working Principle:
The servo motor rotates from 0° to 180°.
At each angle, the ultrasonic sensor sends out sound waves and measures the distance to the nearest object.
The Arduino reads the angle and distance and displays it on the Serial Monitor.
