An obstacle-avoiding robot using an ultrasonic sensor and motor control, programmed with Arduino to autonomously navigate and avoid obstacles by stopping, reversing, and turning.

Google is upgrading the ultrasonic fingerprint biometric sensor for its latest flagship smartphone release. In 2024 the Google Pixel 9 featured an ultrasonic fingerprint sensor for the first time, ...

A novel variable inductor using a bridge circuit is proposed. Because of a bypass switch MOSFET placed at a balance point, the effect of the switch resistance which is a penalty of the variable ...

This paper proposes a small-signal model for average current mode control based on an equivalent circuit. The model uses a three-terminal equivalent circuit model based on a linearized describing ...

The objective of this project is to design and implement an Object Range Detection Sensor system using an ultrasonic sensor and Arduino Uno, as the core controller. This system aims to measure the ...
