The ultrasonic sensor sends a pulse and measures the reflection time. The ATmega32 calculates the distance based on the reflection time. The LCD displays the distance in cm. LEDs and buzzer respond ...

The Wireless Ultrasonic Radar described here is a scaled-down version of a true radar system. It utilises ultrasonic sound waves to detect nearby objects, presenting their precise distance (in cm) and ...

Redmi K80 Pro to feature ultrasonic in-screen fingerprint sensor In the above screenshot, tipster DCS has not mentioned the name of the phone that he is talking about.

So far, all Pixels used optical in-display scanners, and now they're apparently switching to the exact same sensor model that Samsung is using in its Galaxy S24 series.

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...

This Arduino-based Pomodoro timer project also uses this 25-minute cycle. Once you push the button to start the timer, it will run for 25 minutes, display a count-up timer and a "Study time!" ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.
