If you’re reading this, that means you’ve successfully made it through 2025! Allow us to be the first to congratulate you — ...

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 ...

In October 1984 I arrived at Oxford University, trailing a large steamer trunk containing a couple of changes of clothing and about five dozen textbooks. I had a freshly minted bachelor’s degree in ...

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: The main objectives in driving multiple LED strings include achieving uniform current control and high-performance pulse width modulation (PWM) dimming for all strings. This study proposes a ...

This library currently supports any board based on the ATmega168, ATmega328P, ATmega32U4, or ATmega2560 which runs at 8 MHz, 16 MHz, or 20 MHz. The LED strip's input connector has two pins that should ...

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: In this paper, a single-switch coupled-inductor-based two-channel light-emitting diode (LED) driver with a passive regenerative snubber is presented. In the proposed LED driver, the ...
