Aurdino-controlled radar is the subject of this project. A servo motor and an ultrasonic sensor are the essential components of this RADAR system. Components of the system primary role of the system is to detect something. Objects that fall within the specified parameters Ultrasonic sensors are built inside the servo motor. It rotates 180 degrees and uses software to show a visual representation. It's referred to as Processing IDE. A graphical representation of the data is provided by the Processing IDE. The angle or location of the object is also indicated, as well as its distance. This system has already been implemented. It is controlled via Aurdino. An Aurdino UNO board is all that is required to control the system. The sensor's interface with the display device, as well as the ultrasonic sensor during our study of we used current navigation and obstacle detection. Ultrasonic sensors are successfully used in a wide range of inventions and systems. This RADAR system's major applicability is in a range of fields. Navigating, putting, detecting items, mapping, spying, or tracking, as well as a variety of other uses these low-cost systems are also suited for use indoors.
