input PWM signal to counteract the natural exponential nature of the LED to make the LED look like it’s fading linearly. With trial and error, he found the most pleasing input curve to use can be ...

You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has… ...

A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light ...

The design of luminaires for solid-state lighting is still part black art. The best approach starts with the light output and an artistic arrangement of LEDs.
