Santa Clara, Calif. — National Semiconductor Corp. has designed a Boomer light emitting diode (LED) driver that provides audio synchronization without real-time software processing. The LM4970 LED ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...

A white LED delivers a wide color spectrum and better visibility than do monochromatic LEDs. However, a white LED presents a higher forward-voltage drop than do its colorful counterparts and thus ...

To use this driver you will need to enable an SPI peripheral on your chosen mcu or supply your own software SPI routine. For the GD32, you should speficy which SPI port you are using by adjusting the ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

This project demonstrates how to control the brightness of an LED using Pulse Width Modulation (PWM) on an Arduino Uno. The LED smoothly fades in and out by changing the PWM duty cycle on digital pin ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

How hard could it be to turn on an LED? Connect the LED in series with an appropriate resistor and hook it up to a dc source with the correct polarity and voilà, instant LED light. Of course, you can ...
