	# Modified adalight arduino version which uses the FastLED ( http://fastled.io/ ) library.
	# I found this code at https://forums.adafruit.com/viewtopic.php?f=47&t=59464#p301431 .
	# For me it works much more smooth then the original code using SPI.h .
	# It works pretty well with Colorswirl boblight and hyperion
