Reverse Engineering the iColor Flex Protocol

Posted on November 17, 2019 by Glen

Back in the early 2000’s–at least a decade before there were Neopixels or WS2812b LEDs–Color Kinetics introduced flexible color changing LED string lights. Each string contained fifty RGB color changing nodes. Each node contained an RGB LED and a custom … Continue reading →
