Design and Implementation of Ultrasonic Radar Using Arduino
This project presents the design and implementation of an Ultrasonic Radar System using the Arduino Uno, buzzer and the HC-SR04 Ultrasonic Sensor. The system is developed to detect objects and determining parameters such as distance, position, direction, speed and range which can be either in fixed or to be in motion. The ultrasonic sensor emits high-frequency sound waves and receives the reflected echo from objects. The Arduino Uno calculates the distance using the echo time-of-flight principle. A servo motor rotates the sensor from 0° to 180° to scan the area, and the measured distance and angle data are displayed on a computer as a radar-like visualization. If the object is detected then the buzzer sound will be activated. This system provides a simple, cost-effective, and efficient method for real-time object detection and distance measurement. It can be applied in obstacle detection, robotic navigation, security systems, and automation projects. The project demonstrates the practical use of embedded systems, sensor integration, and real-time data visualization.
