Arduino 360° Ultrasonic Radar Science Project

Advanced 360 Degree Ultrasonic Radar Detection System Arduino Project

This 360° Ultrasonic Radar Detection Project is a complete, ready-to-use Arduino-based science project designed for students, hobbyists, and science fair participants in Bangladesh. Built using dual HC-SR04 ultrasonic sensors mounted opposite each other and controlled by a rotating MG90S servo motor, the system achieves full 360-degree environmental scanning. It detects objects within a range of 0–50 cm and provides an alert when an object comes within 20 cm using an active buzzer.

The project connects to a computer via Arduino and displays a real-time graphical radar interface using Processing software. This allows users to visualize both the distance and direction of detected objects, making it highly educational and visually impressive for science fair submissions. At Biggan Project, this system is designed to meet the needs of students in BD who want a professional-looking and functional science project.

This project is not just a display model—it demonstrates real-world concepts such as distance measurement, angular scanning, sensor integration, and data visualization. It is ideal for students in Bangladesh looking to stand out in science fairs or academic project submissions.
