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 ...
The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...
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, ...
Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (March 2026) that make the cut: ...
Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...
Crystal jellyfish have an eerie beauty: thanks to a natural protein, they emit a faint green glow. For decades, researchers have used that green fluorescent protein and similar molecules to light up ...
If you’ve used Linux for a long time, you know that we are spoiled these days. Getting a new piece of hardware back in the day was often a horrible affair, requiring custom kernels and lots ...
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 ...
