Arduino Nano H C-SR04 ultrasonic sensor SG90 servo motor 1.8″ ST7735 Display (or equivalent) Soldering kit Screwdriver set 9V battery and connector Electrical wires and soldering gear.

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 ...

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 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!" ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Arduino Uno – Powered Parking Guidance System with Ultrasonic Sensors" is a smart and innovative solution for simplifying the parking process in crowded urban environments. This paper leverages the ...

The new HTU200 and DMU200 series of compact ultrasonic sensors detect objects regardless of their surface structure using a reflected acoustic pulse. These switching and measuring ultrasonic sensors ...

Goodix, a prominent player in the technology industry, is set to roll out its ultrasonic under-display fingerprint sensor for mass production by the end of this year, according to Digital Chat ...
