This project uses a servo motor and ultrasonic sensor to continuously scan surroundings. It detects movement by measuring distance changes and triggers an alarm with a buzzer if significant variations ...

This project implements a simple radar system using an Arduino Uno, an ultrasonic distance sensor, and a servo motor. The radar scans an area by rotating the ultrasonic sensor with the servo and ...

Abstract: This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display ...

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 ...

Sometimes, it’s time to shut down the oscilloscope, and break out the cardboard and paints. If you’re wondering what for, well, here’s a reminder of an Instructable from [CrazyScience], that brings us ...
