These days, addressable LEDs are all the rage. A little chip paired with each LED receives signals and modulates the light output as needed. [John Peterson] was working on a project along these ...

Multiple LEDs at once from your driver chip, using a higher voltage. We are taken through a bit of the background to perceived intensity and gamma correction for the human eyesight.

Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” method as an ...

Using an Arduino Nano microcontroller together with addressable RGB LEDs, the tabletop version of the wall-mounted original Domino clock offers a great way to learn more about controlling LEDs ...

The new OSIRE® E3731i RGB LED features a digital core that enables low-latency communication over a standard serial bus interface with any microcontroller. ams OSRAM has also developed a new Open ...

To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller.
