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 ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

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 ...

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 ...

Sunpower’s DAP-04 DALI to PWM converter is designed to provide DALI control in LED lighting applications. The DAP-04 has a DALI input that can accept data from a remote IEC62386-101, 102 or 207 ...

Melexis, the Belgian auto IC specialist, has launched a multi-channel LIN RGB LED controller with 24 LED driver outputs each capable of sourcing up to 60mA. Capable of driving eight RGB channels, the ...

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 ...

Linear Technology has unveiled a new pulse width modulation (pwm) generator with 48 independent channels. According to the IC specialist, each channel has an individually adjustable 12bit (4,096 steps ...

NZXT has launched a new range of RGB illuminated PC system fans. Available in both 120mm and 140mm sizes, the Aer RGB fans feature fluid dynamic bearings, PWM control, and RGB lighting effects ...
