Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...

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 ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

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.<br><br>I am trying to build a simple circuit to simulate the ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...
