This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...

Some 1.5 v LED flasher circuits are available on the internet and we like to present you four of them. The flasher circuits below operate on a single 1.5 volt battery. The circuit on the upper uses ...

The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs.

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

They look for all the world like any other LED, though embedded in the plastic dome is an integrated circuit to do all that flashing work. There was a time though when a flashing LED was something of ...

Discover the step-by-step process of creating a powerful music reactive LED strip circuit in this comprehensive tutorial. This video will guide you through the essential components and techniques ...

Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...

In addition to a likely improved processor and camera sensor, it appears that Apple’s next-generation iPhone will include a dual-LED Flash. In light of reports and part leaks pointing to this new ...
