Is someone on your list hard to shop for? We've got a ton of great options for just about anyone. And grab a little something ...

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 ...

Buying a monitor or TV has become a daunting task these days. When manufacturers aren’t branding their products with acronyms like QLED and OLED, they use confusing terms like mini-LED instead.

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 ...

Abstract: This article proposed a novel design for the monolithic micro-LED array, directly integrated with a sapphire microreflector. Its resolution was 300 dpi. Theoretically, each micro-LED pixel ...

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, ...

There’s a type of dust-collector that’s been popular since the 1990s, where a cube of acrylic or glass is laser-etched in a three-dimensional pattern. Some people call them bubblegrams. While it could ...

Abstract: A majority of luminance measurement systems are currently focused on measuring the total luminance of light-emitting diodes (LEDs). It has largely limit its application on micro-LEDs, which ...

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 ...

The LED matrix 8x8 is a system of 64 interconnected LEDs that, with the help of the MAX7219 LED driver, light up as programmed, and all of this is located on one board and is truly easy to use. You ...
