Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...
WiFi and Bluetooth LE can now be used simultaneously on Arduino boards with NINA-W102 (ESP32) module
Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...
Abstract: Ultrasonic waveguide techniques are most familiar to monitor temperatures in the hostile environments. A single waveguide could be used as multiple sensors. In the present work, a thin strip ...
