Servo Motor Radar with Ultrasonic Sensor - DIY Arduino Project

Build your own Arduino radar system using a servo motor and an ultrasonic distance sensor (HC-SR04). This DIY project scans a 150-degree range, detecting objects within 15 cm and triggering an alert system with blinking red LED and a buzzer sound. When no object is detected, green LED stay on, indicating a safe zone. Perfect for Arduino beginners, home security experiments, and motion detection projects. Watch as the servo sweeps smoothly, creating a real-time scanning radar!
