Knowing how to calculate an LED current limiting resistor is one thing, taking into account all other sorts of parameters as well is another. In Part 1 you learned how to calculate a current limiting ...

LEDs are a staple component in most circuits. Using Ohm’s law, we can easily calculate the conditions for the theoretical lighting intensity we’re after. LEDs are a staple component in most circuits.

AC LED driver circuits are overly popular due to the advancement of High current white LEDs. We already made a Transformerless LED driver circuit previously, but in that circuit, we used a dedicated ...

The basic circuit illuminates up to ten LEDs in sequence, following the rhythm of music or speech picked-up by a small microphone. The expanded version can drive up to ten strips, formed by up to five ...

LEDs are more efficient than incandescent lights and can last 100 times longer, but they require specialized electronic-drive circuits to avoid overstress conditions. The main operating parameter is ...
