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 ...

The growing demand for color displays in cell phones, digital cameras and PDAs has created a huge market for white LEDs as backlights in these applications. Because white LEDs require low dc voltage ...

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 ...

Today’s drivers with two or more independent LEDs (ILEDs) can control a portable system’s fun light (multiple light sequences with several colored LEDs to make a phone, say, more attractive to a user) ...

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 project is so pretty in its own right, it doesn’t need a case! Clocks are a recurring feature among the projects we feature here on Hackaday, with several common themes emerging among them. We ...
