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 ...

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 ...

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 ...

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 ...

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 ...

DETROIT -- Your next car’s headlights could be brighter and more focused, illuminating farther down the road but continually shifting to avoid shining into the eyes of other drivers. Multi-LED ...
