Arduino 360° Ultrasonic Radar Science Project

Arduino Based 360 Degree Ultrasonic Radar Detection Project This 360° ultrasonic radar project is a complete Arduino-based science project designed for students and science fair submissions. Using dual HC-SR04 sensors and a rotating servo system, it scans the surroundings and detects objects within 0–50 cm. When an object comes within 20 cm, it triggers an audible alert. The system also provides a real-time graphical radar display through Processing software, showing both distance and direction clearly. Specifications Controller: Arduino Uno R3 SMD Sensors: 2x HC-SR04 Ultrasonic Sensor Rotation: MG90S 180° Servo Motor (dual-side scanning for 360°) Detection Range: 0–50 cm Alert Distance: 20 cm with active buzzer Display: Real-time radar visualization using Processing software Structure: 5mm PVC board frame Wiring: Flexible project wires Cable Management: Nylon cable zip ties Assembly: Hot glue gun sticks
