Smart Stop is a compact, low-cost safety system that uses an ultrasonic sensor to detect obstacles and automatically control motor speed. It provides real-time feedback through LEDs and an LCD display ...

The ultrasonic distance sensor (HC-SR04) is a widely used electronic component for non-contact distance measurement. It operates on the principle of echo-ranging, where it emits an ultrasonic pulse ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting ...
