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 ...

Welcome to the Basic Arduino Projects repository! This project contains a collection of beginner-friendly Arduino circuits simulated using Tinkercad Circuits. It is intended for students, hobbyists, ...

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 ...

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 ...

Abstract: Miniaturized vision-based tactile sensors (VBTSs) are essential for compact and high-resolution surface perception in constrained environments. However, conventional lens-based imaging ...

Abstract: We fabricated a curved complementary metal-oxide semiconductor (CMOS) image sensor to demonstrate field curvature aberration correction of lens without the use of multiple lenses. An ...
