This project is a simple automatic toll gate system built using Arduino, an ultrasonic sensor, a servo motor, and a 16x2 LCD display. The system detects when a vehicle approaches the gate, opens the ...

int max_ultrasonic_distance_cm = 400; // set the maximum measureable distance for the ultrasonic sensor to 400cm NewPing sonar(ULTRASONIC_TRIGGER, ULTRASONIC_ECHO ...

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 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 Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

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

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 ...

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 ...

Engineers at the Korea Research Institute of Standards and Science (KRISS) have developed a new ultrasonic sensing technology that can detect structural defects in dangerous environments where ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...
