[Garrett] took 30 of his ShiftBrite modules and mounted them to his front fence for Christmas. The ShiftBrite is a serially addressable high output RGB LED. The individual modules are quite adept at applications like this where you’re stringing multiple lights together. They have identical buses on either side, specifically for daisychaining. The installation above looks great.
We made a point to stop by [garrett]‘s booth at Maker Faire to to see what he had been working on. You may remember him from his random caps locker shenanigans. He’s just recently released the ShiftBright RGB LED module which makes it easy to implement a string of individually addressable LEDs. The module is based on the Allegro A6281 3-Channel Constant Current LED Driver. The driver chip is capable of displaying a billion colors using an RGB LED. The 3x3mm package is mounted to the backside of the board while a bright common-anode RGB is mounted to the front. The modules are designed to be daisy chained together and are individually addressed using a serial interface. You can find Arduino example code on the site and more info on how the item was developed. Read on for close up images.
