Immediately sets desired colour, with optional callback function.

Fades to desired colour linearly, over time ms. Optional callback.

First, fades to startColour over fadeTime ms as with .fadeRgb, but then fades back and forth between this initial colour and endColour. In this case, pulseTime is the time in ms fading from one colour to the next, e.g. the total period is 2*pulseTime.

Stops the pulse effect.

Creates a stroboscope effect where the output is either switched off, or set to colour. This switch happens every pulselengthms, for a total duration of durationms. Optional callback.

Shuts down the PWM channel.
