LED Modules: The LED works on very simple phenomena where voltage is applied to a semiconductor material to make electrons run loose from the material – in return, light energy is emitted in the form ...

Usually, the common anode of the LED package is the second pin from the flat side of the LED package. It is also the longest of the four leads. This lead will be treated as the “common” pin of the RGB ...

This module introduces Pulse Width Modulation (PWM) techniques for Python on the Raspberry Pi. Subsequently, by using PWM we can modify the brightness of an LED without having to change a resistor.

ShiftBrite RGB LED module (Macetech, $4.99). ShiftBrite datasheet and example code, Allegro A6281 datasheet (PDF). The ShiftBrite module is a complete A6281 development board.

Seoul’s NanoDriver Series LED drivers, based on the company’s patented Acrich design, enable integration of the AC modules’ control circuitry into a miniature driver package, which provides ...

To be honest, while it was a complete module and it made an overall good impression, the documentation made me a bit wary. Looking closely at the little circuit board, I noticed that it’s based on a ...

So he decided to add an 8×8 LED module which would display the load for each individual core of his CPU. It looks great next to the illuminated tachometer.

Each comes with an identical LED array with an integrated LED driver that generates an unprecedented luminous flux in an area of only 12.8 millimeters (0.5 inches) by 3.2 millimeters (0.12 inches).
