A controller IC drives high-brightness LEDs for a variety of indoor, outdoor, and automotive applications. Its LED system design is simplified by the use of an online program. Housed in a 20-pin ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer. Suppose a manufacturer recommends a maximum voltage ...

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 ...

When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...
