The Arduino-Based Ultrasonic Radar Detection System is a simple electronic project that detects objects and measures distance using an ultrasonic sensor and Arduino UNO. A servo motor rotates the sensor from 0° to 180°, allowing the system to scan the surrounding area like a radar.
When an object is detected within a preset range, a red LED turns ON and a buzzer sounds as an alert. If no object is detected, a green LED remains ON. The detected angle and distance are sent to a laptop through serial communication and displayed as a radar-style visualization using Processing software.
