In part one of this series, we looked at the basics of LED lighting sources and their driving requirements. In part two, we discussed why a constant-current buck converter should be your first ...

From what you would gather from Hackaday’s immense library of builds and projects over several years, the only way to do PWM is with a microcontroller, some code, a full-blown IDE, or even a real-time ...

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.

This is yet another project born of necessity. It’s a simple circuit, but does exactly what it’s designed to do – dim LED lights or control the speed of 12V DC motors. The circuit uses PWM to regulate ...

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 ...

I'm trying to dim LED strips, approximately 30ft in length, with hand controls. I've found that regular potentiometers (those sold by Adafruit) max out at about 0.2 W. For whatever reason, the Red ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

DXOMARK tested the Google Pixel 9’s display and ended up praising it. I was interested the moment I saw the results, as the Pixel 9 has really low PWM dimming, unlike many of the competitors. The ...
