This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...

Arduino---Joystick-Controlled-Servo-with-Ultrasonic-Object-Detection This project combines a joystick, servo motor, ultrasonic sensor, two LEDs, and a buzzer to create an interactive object detection ...

The post Exclusive: Google Pixel 10 to get New, Faster Ultrasonic Fingerprint Sensor appeared first on Android Headlines.

In this paper, we build a micro-ultrasonic motor in the 2–3 mm scale, combine it with a tunneling magneto resistance (TMR) sensor with dimensions of 1.4 mm ×1 mm, and construct a closed-loop system ...

A cantilever ultrasonic motor with nanometer resolution is designed, fabricated, and tested in this article. Two orthogonal first bending vibration modes are used to form elliptical movements on ...
