This circuit can flash three sets of LEDs with different levels of Flashing. It can be used as Ornamental displays. The circuit uses a simple Astable multivibrator built around the popular timer IC ...

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), ...

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 ...

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 ...
