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 ...

In this series I will be documenting my design and testing process for making a 3D printed arduino hexapod. This video sets up the basic premise of the project with a quick test of a servo controlled ...

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic sensor technology that applies a waveguide to detect defects in all directions without ...

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 ...

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, ...

NEW projects in hilly areas in Ampang Jaya, Selangor, will be required to instal Early Warning Systems (EWS) as part of their development conditions. Ampang Jaya Municipal Council (MPAJ) deputy ...

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: Robotic Continuous Ultrasonic Welding (cUSW) provides significant advantages, including efficiency, flexibility, and the capability to weld complex geometries with high repeatability. These ...
