Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Here's a way to accomplish the task that's simpler than other methods. Driving multiple LEDs with one microprocessor ...

An on-chip circuit that can produce up to six microwave photons simultaneously has been created by researchers in France and Germany. Gerbold Ménard and Ambroise Peugeot at the University of ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

If you’ve worked on a project with small LEDs, you know the frustration of determining their polarity. This ingenious LED Probe from [David] packs a lot of useful features into a simple, ...

Light-emitting diodes have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...
