LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

The traditional way to control the output of multiple LEDs is to dedicate a pulse width modulation (PWM) controller to each LED and use the controller to transform the input voltage to a current that ...

Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Typically, designs perform this task by issuing pulse widths and clocks of differing durations and employing multiple ...

This application note gives some examples how to emulate multiple lamps using one MLX1003 LED driver. By modifying the current that is controlled by one LED driver, multiple lamps can be emulated. A ...

Driving an LED and making it flash is probably the first project that most people will have attempted when learning about microprocessor control of hardware. The Arduino and similar boards have an LED ...

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 ...

The backlighting system of MacBook Pro keyboards could be upgraded to include TrueTone capabilities, with Apple examining the use of multiple LEDs per key to make the light seem even despite changes ...

The energy efficiency, longevity, and versatility of light-emitting diodes (LEDs) have made them popular in various applications, including lighting sources in homes, offices, automotive, and ...

Excellent quality, ruggedized, lightweight, superb output are key descriptors for the Cyclops Adventure Sports Long Range Optimus Prime LED Light Kit. This kit has two lights, one with a 10 degree and ...
