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 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 ...

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.

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

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 ...

An LED chaser or LED running light can be used as a decorative light, fancy light, chasing taillight for vehicles, etc. The circuit consists of a 555 astable multivibrator circuit and a 4017 counter ...
