Visual Radar Project

Overview

This project demonstrates a visual radar system using Arduino and Processing. The radar system measures the distance of objects within a certain range and visualizes the data on a computer screen using a radar-like display. The system utilizes an ultrasonic sensor connected to an Arduino to detect distances, which are then sent to a computer via serial communication. The Processing application reads these values and displays a real-time radar view.
