Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED's are used in many applications.

I know very little about electronics, but if you give me a schematic and a pile of parts, I can more-or-less assemble them correctly.I am trying to build a simple circuit to simulate the behavior ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be ...

3V is sufficient to turn on any LED, but is within its reverse break down voltage rating (that is why I did not use the common 9V battery). Short circuit current is approx. 30mA. I used a 3V lithium ...

Her tutorial covers a simple LED circuit with a battery and a sliding switch, though she describes in detail how this can be expanded for more complex circuitry and offers good suggestions for ...

In the industry, I have found that an LED ballast circuit is really more like an AC/DC power supply than like a traditional fluorescent ballast circuit. Today in fluorescent lighting, one need ...

October 9, 2013 [Henryk] just sent us his latest episode of simple LED circuit puzzles. In front of the camera he solders one pin of each of the 3 LEDs to a different switch.
