pattern.color_sequence(targets, ramp_time=10)

Generate a color sequence.

Parameters:

• targets – Target colors e.g. [‘red’, ‘blue’, ‘green’]
• ramp_time – Time to ramp up to target RGB.

Returns:

Color sequence generator. This generator is infinite and continues to return the last value once the

variable components are complete.

pattern.pulse_rgb(rgb, loop_time, frequency=1, decay_time=None)

Pulse the RGB channels.

Parameters:

• rgb – The target RGB e.g. (255, 0, 0)
• loop_time – The time between each loop call e.g. 0.1s
• frequency – The frequency of the pulse (default 1Hz)
• decay_time – The amplitude decay time (s)

Returns:

A generator.
