Each pattern has multiple modifiers which can drastically change its appearance.

The following videos are taken with the default values.

Equation

You can input a custom equation for the rgb values. Such equation can depend on:

• time: a time-step is kept so to evolve the function through time
• index: the position of the led-strip can also be used

For example the following patters is given with:

• red = cos(t)
• green = sin(t)
• blue = idx

Music Reactive (click gif for video)

This pattern uses a microphone to visualize the music on your led strip. There are three different type of visualization:

• Spectrum: split the strip on subsequent frequency bands and visualize the amplitude as a mix of rgb values
• Energy: use an energy function to plot the sound on the leds
• Scroll: record the audio amplitude on a scrolling timeline.

Designing a pattern can become hard and take some time, so why not using a pre-made pattern?
