[Patrick] was prepping for some future projects he had in mind, for which he will need a simple 2D array of addressable LEDs. While it is certainly possible for him to build his own LED array and ...

Woman installing an LED light bulb into a fixture - Goodlifestudio/Getty Images LED (light-emitting diode) bulbs are longer-lasting and more energy-efficient than their incandescent counterparts. But ...

Recently, I was working on a project that needed a couple of LEDs on its front panel for status indication. I realize many, if not most, pieces of electronic equipment now use graphic LCDs, Bluetooth ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...

An LED is commonly used as a "power on" indicator for many electronic devices. For the LED to produce discernible visible light in daylight, the forward-bias current needs to be in the moderate range ...

INDIANAPOLIS — Welcome to Home Zone! Today, we’re upgrading outdoor lighting with an easy and modern solution — plug-in LED lights. If you’ve been dealing with old, unreliable transformer-style lights ...

Some of the climate activists might have you believe LED light bulbs are the greatest invention since sliced bread and are simple drop-in replacements for incandescent bulbs. They need to do their ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

LED (light-emitting diode) bulbs are longer-lasting and more energy-efficient than their incandescent counterparts. But that doesn't mean they last forever. If your LED bulbs are burning out well ...
