A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...
In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...
The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...
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 ...
In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...
Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (March 2026) that make the cut: ...
Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based ...
Named after the Italian word for "21," Ventuno Q is Qualcomm's first attempt to soothe the wary Arduino community. The UK chip designer acquired the Italian ...
ROS Laser Bot is a ROS Kinetic autonomous navigation project for TurtleBot using the Stage simulator and a Hokuyo laser model. It implements three smooth controllers—basic, advanced, and TF-based—to ...
