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 ...

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 ...

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 ...

If you’ve ever witnessed or been part of the team of AV installers assembling and mounting an LED tile display, you know it can be an arduous process. Not only does each panel need to align perfectly ...

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 ...

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 ...

If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, ...

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 ...
