StripSerial
Rainbeau test sketch for strip of addressable RGB LEDs.
Requires http://fastled.io/ library.
Updated with optional remote serial control from PC. Six26 (talk) 22:19, 12 September 2014 (UTC)
/*
* Serial control interface for LED Strip
* Command Summary:
* MODE0 == Auto (Rainbeau)
* MODE1 == Off
* MODE2 == Remote (PC Control)
* HH..H == Sequence of Hue values to apply to LEDs
* Note: Set "MODE2" before sending hues
