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 ...

This allows the lighting systems to achieve an LED brightness contrast ratio of 15,000:1 using PWM-only dimming at 200 Hz. Moreover, a higher contrast ratio of 150,000:1 is possible with a combination ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does ...

Parallel LED drivers can be used to create the fast, square, high-current waveforms required for automated image processing. And it’s possible to extend such waveforms to higher currents by connecting ...

Whether you want to keep your fish happy or just need a good light show, this aquarium light fits the bill. It is the second iteration, but [William] calls it v1. That’s because v0 — which used a few ...

OLED screens use PWM dimming to adjust brightness, basically flickering the display really fast. For some people, that flicker leads to eye strain. Lately, phone makers have been tackling the issue by ...
