blink1.version(callback(version))

Fade to RGB, optional callback called after fadeMillis ms:

blink1.fadeToRGB(fadeMillis, r, g, b, [callback]) // r, g, b: 0 - 255

Set RGB:

blink1.setRGB(r, g, b, [callback]) // r, g, b: 0 - 255

Set server down (enable, disable), optional callback called after millis ms:

blink1.enableServerDown(millis, [callback]) // tickle

blink1.disableServerDown(millis, [callback]) // off

blink1.play = function(position, [callback])

Pause (stop playing the pattern line):

blink1.pause = function([callback])

Write pattern line (set the parameters for a pattern line, at the specified position):

blink1.writePatternLine(fadeMillis, r, g, b, position, [callback]) // r, g, b: 0 - 255
