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 ...

The circuit uses a Vishay V34836 infrared receiver to pick up the invisible signals that are sent from a remote control. A Microchip 12F683 processes the data and has two main output modes.

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...
