Abstract


A radar system using Arduino involves the develop- ment of a simple, yet effective radar sensing mechanism that leverages Arduino microcontroller boards for signal processing, control, and communication. The system typically uses ultrasonic or radio waves to detect objects, measure their distance, and track their movement. The Arduino processes the reflected signals received by a sensor, calculates the time delay, and then computes the distance of the detected object based on the speed of sound (in the case of ultrasonic radar) or the speed of light (for radio frequency radar). This type of radar system can be used for a wide range of applications, including obstacle detection in robotics, proximity sensors, and even basic weather forecasting. The advantage of using Arduino in such systems is the accessibility, ease of programming, and cost-effectiveness, making it an ideal platform for prototyping radar technology and understanding the fundamental principles of radar signal processing and distance measurement.
