Yet Another Arduino Radar This script will control the rotation of a servo motor, which will in of itself rotate an ultrasonic sensor. It will then scan for distance every degree spun. The collected data will be mapped onto an embedded screen in a radar-tracker-like view.

The blue line's length symbolise the distance of the object: longer lines mean a further object. When an object is scanned over, yellow text in the corner of the screen displays the precise distance of said object.
