        abstract = {his project details the development of a 360-degree radar system utilizing an Arduino Uno microcontroller, two ultrasonic sensors, a servo motor, a buzzer, and an LED. The system aims to provide a comprehensive spatial awareness solution by detecting objects within a specified range and displaying their relative positions through visual and auditory cues. The servo motor, controlled by the Arduino, rotates the ultrasonic sensors in a full 360-degree sweep, allowing for continuous monitoring of the surrounding environment. The two ultrasonic sensors are strategically positioned to enhance detection accuracy and minimize blind spots, providing redundancy and improved angular resolution. Distance measurements from the sensors are processed by the Arduino, which then calculates the object's distance and angle relative to the system's origin. The LED serves as a visual indicator, illuminating when an object is detected within a user-defined threshold distance, while the buzzer generates an audible alert, escalating in frequency as the object approaches closer. The Arduino code incorporates a systematic scanning algorithm that manages the servo's rotation, acquires sensor readings, and translates the data into actionable outputs for the LED and buzzer. The system's design emphasizes simplicity and cost-effectiveness, leveraging readily available components to create a functional radar system suitable for various applications, including obstacle avoidance, proximity detection, and robotic navigation. The project's modular design allows for future enhancements, such as integrating a graphical display for a more detailed representation of the surrounding environment or incorporating more advanced signal processing techniques for improved accuracy and noise reduction. The final system provides a robust and reliable 360-degree spatial awareness solution, demonstrating the versatility of the Arduino platform in developing practical sensing applications.},
