IKEA has launched its new Gömpyssling LED light with sensor. It's a motion-activated light which automatically switches on when you open a cupboard or step into a space, then turns itself off after ...

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 ...

Patients are being warned to stop using some glucose monitors made by Abbott Diabetes Care after the company found malfunctioning sensors may be linked to hundreds of adverse events and several deaths ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

A series where we find out which products the professionals (who really know what they’re talking about) actually use and really stand behind. Read more here. Maybe you’ve seen an influencer gliding ...

Many people believe that the LED was discovered by US researchers working in the 1960s. In fact, Henry Round at Marconi Labs noted the emission of light from a semiconductor diode 100 years ago and, ...

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 ...

Abstract: Accurate indoor positioning is becoming increasingly important, especially in highly automated industrial environments with robots. In addition, LED-based lighting is also being used more ...

Project Description This project uses YOLOv8 for object detection and an Arduino Uno (or Mega) to control an LED. If an electronic device is detected in the camera feed, the LED glows. The system ...

Abstract: This paper presents a proof-of-concept image sensor with triple functionality: sensing, energy harvesting and image projection. This triple functionality is achieved by employing light ...
