This LED rainbow project creates a RGB LED PWM controller with minimal amount of components including a PIC processor. This LED rainbow project creates a RGB LED PWM controller with minimal amount of ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

Diodes Incorporated (Diodes) (Nasdaq: DIOD) introduces the AL3069Q, an automotive-compliant* high-efficiency 60V boost controller for backlight applications. The device includes four 80V ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

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 ...
