[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...

One of the questions that hobbyists ask over and over is how to select the value of a current limiting resistor for an LED. Usually the seat of the pants response is ...

The ubiquitous LED continues to expand frontiers and applications with a plethora of sizes, colors, and output lumens. Flashing LEDs that incorporate internal ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

In this article, I would like to talk a little bit about LEDs, including why they will become the lighting source of choice, how to power them and also, how to protect them from the hazards they face ...
