Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

It turns out the "10-year lifespan" printed on your LED box is often a total fantasy. I spent years falling for the marketing, only to end up standing on a ladder every six months replacing bulbs that ...

Abstract: We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

This Arduino library provides a convenient and easy-to-use interface for the PH4502C sensor, allowing you to effortlessly integrate it into your Arduino projects. The PH4502C sensor is a ...

Abstract: Key requirements to boost the applicability of ultrasonic systems for in situ, real-time operations are low hardware complexity and low power consumption. These features are not available in ...

Is a human micro-motion sensor that can detect and recognize moving, standing, and stationary human body. The code in this library is based heavily off this LD2410, Waveshare and RD-03 documentations.
