This library is using a hardware interrupt to monitor Echo pin state change instead of using pulseIn function which pauses code execution. The library enables the user to use this sensor with only 2-3 ...

Focus on One Area: Robotics is broad. You could focus on programming first, then move to electronics, or vice versa. Trying ...

I still vividly remember the first time we observed neurons responding not to audible sound, but to concentrated, precisely ...

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it uses rgb LEDs that are controlled by an Arduino-based microcontroller that ...

Olimex HoT (Home of Things) is a lightweight Smart Home solution designed to run on low-end hardware (128MB RAM, 128MB flash) ...

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

The Sharp GP2AP03VT00F Time-Of-Flight sensor seems to be a nice part for makers and roboticists, focusing on good short distance sensing where other parts sometimes have problems. Alas, Sharp seems to ...

Japan's nuclear regulatory system faces unprecedented scrutiny after a devastating security breach involving classified information. A Nuclear Regulation Authority official's ...

Abstract: In this paper, we propose the use of ultrasonic sensors for autonomous parking systems. In general, LiDAR sensors are evaluated to be advantageous in autonomous parking systems, but this ...

Abstract: An optical fiber ultrasonic coupling sensor enhanced by a resonant cavity is design and optimization in this work. By using the prestressed bonding method, the structure consists of optical ...
