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 ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

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 ...

In our tips line we sometimes receive hacks that are amazing just because of their ingenuity. This relay-powered flashlight is definitely one of them. It has been named RattleGen by its creator [Berto ...

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 ...

Diodes has released simple LED driving chips for regulating current in strings of LEDs, particularly in cars and other road vehicles – some of which match parts from Infineon and Nexperia (see table ...

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 ...

Supertex has introduced an LED lighting chip with switch dimming. The IC, dubbed HV9801A, dims LED lamp brightness to one of four preset levels through rapid toggling of a light switch. Light levels ...

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 ...

Somewhere along the line, consumer display technology became an alphabet soup full of terms using the letters “LED.” In this succinct guide, we’ll provide a brief overview of common initialisms found ...
