The original LED strip had a simple battery box with an on/off switch, which had a dodgy connection - instead of fixing it, I replaced it with a a Trinket M0 and a push button to toggle between 5 ...
This app note provides a simple circuit to drive high brightness LEDs. It requires minimum external components and it provides both linear and PWM dimming. Ideal for Osram, Lumileds, Cree, and Nichia ...

I was puzzling over the classic bistable circuit and wondering if it was possible to expand it to any number of channels. And this is what I came up with. BTW: To make it more interesting (claims I), ...
Many portable appliances and other products that must operate from a single cell are restricted to working at very low voltages. It is thus difficult to drive white LEDs that typically have a forward ...
Most commercial LED flashlightsuse three AAA or AA batteriesin series that produce 4.5V. The batteriesthen drive four white LEDs that connectin parallel. These LEDs can workat voltages as low as 2.7V ...
Abstract: A monolithic pulse frequency modulation control DC-DC boost converter, which is suitable for white LEDs driver integrated circuit, is presented in this paper. The proposed boost converter is ...
If you’re looking to control WS2812 (or Neopixel) LEDs using a microcontroller running at 3.3 volts, you might run into some issues. The datasheet tells us that a logic high input will be detected at ...
