This project implements a real-time closed-loop motor control system where motor speed is dynamically regulated based on obstacle distance. An ultrasonic sensor provides the reference input, an ...

Simple distance measurement project using an HC-SR04 (or compatible) ultrasonic sensor with the Arduino Uno R4 WiFi board. The sketch reads distance and prints it to the serial monitor.

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (February 2026) that make the cut: ...

Scientists have just found a new way to track the uncontrolled reentry of falling space junk. As they punch into the atmosphere, chunks of space debris create sonic booms that can be detected by ...

More than 120 seismometers detected sonic booms from space debris and enabled its fall to be tracked with unprecedented ...

Scientists have found a new way to track falling space debris using earthquake sensors. According to a new study published in the journal Science on January 22, 2026, under the title Reentry and ...

Unfortunately, hail and sleet are far from the only falling objects that may come crashing down on you—you may need to watch out for the growing problem of plummeting space junk. As the number of ...

We break down real-world differences in comfort, codecs, transparency, smart features, and battery life to reveal which flagship earbuds best fit your lifestyle.

ST’s VL53L5CX is a very small 8×8 grid ranging sensor that can perform distance measurements at a distance of up to 4 meters. In a recent video,[Henrique Ferrolho] demonstrated that ...
