Object Detection Radar with Arduino Uno

Abstract: The advancement of embedded systems and sensor technology has enabled the development of low-cost radar systems for object detection and distance measurement. This project, “Object Detection Radar with Arduino Uno,” presents a compact and efficient system designed to detect objects within a defined range using ultrasonic sensing technology. The system is built around the Arduino Uno microcontroller, which processes distance data obtained from the HC-SR04 ultrasonic sensor and visually represents the detected object on a servo-mounted radar interface. The rotating servo motor enables the sensor to scan a 180-degree field, while the Arduino calculates the distance based on the time delay of the ultrasonic pulse reflection. The detected objects are graphically displayed on a computer screen using Processing IDE, simulating a real radar system. This project demonstrates how radar principles can be implemented using affordable electronic components, making it a valuable educational and practical tool for understanding distance measurement, obstacle detection, and embedded system integration. The proposed system has potential applications in robotics, vehicle collision avoidance, security systems, and automation. Overall, the design highlights the effectiveness of combining ultrasonic sensing with microcontroller programming to achieve real-time object detection and visualization..
