The flasher circuits below operate on a single 1.5 volt battery. LED flasher circuit diagrams The circuit on the upper uses the popular LM3909 LED flasher IC and requires only a timing capacitor and ...

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 ...

In Figure 1, National Semiconductor's LM3710, a supervisory circuit, is configured to reduce the power consumption of a traditional LED indicator by 99%.

With this circuit you can flash some LEDs for your rc airplanes or any other uav just like the real strobe navigation lights ...

[Collin] demonstrates this technique in the video, constructing a simple LED flasher circuit. He says that the process works decently enough, and was kind of fun to do.

Need a pulse stretcher for an application like an LED flash? James Campbell does it using TI's configurable multifunction logic gate.

These days, if you want to flash some LEDs, you’d probably grab a microcontroller. Maybe you’d go a little more old-school, and grab a 555. However, [Jacob] is even more hardcore than t… ...

Chibitronics combines familiar adhesive stickers with bits of LEDs, sensor circuits, and even a programmable microcontroller, to create a playful set that educates while adding some flash to one ...
