Is there a list of all the FastLED functions, keywords, etc,

Is there a list of all the FastLED functions, keywords, etc, someplace (preferably with explanations). I don’t mind hammering away at trial and error arduino coding – to avoid tying up other people’s time – but it would be nice to know what you can ask FastLED to do and how.

For example, it shouldn’t be too difficult to get the rows on a grid/matirx to light up and move from bottom to top – but impossible if you don’t know what does and doesn’t exist.


Thanks Jason. Those might be of some help. I guess what I’m really looking for is the dummies guide to FastLED. :slight_smile:

I’ll keep hammering away and trying different things to see what they do!

What kind of matrix and microcontroller are you using? I’d start with the blink example: and then maybe move on to Cylon:

No matrix yet… just strips. I’ve been playing with all the sketches I can find, and then trying to make small changes and see what the result is. Using a Mega 2560.

Eventual goal is a set of panels that can be worn to create an LED “suit”. However, I want panels to that they can be removed (not attached to clothing that can get dirty and need washing) and adjusted for size. Preliminary thought is a panel/matrix on both shins, both thighs, both forearms, both biceps, and one on the chest. An cool display example would be a “pulse” of light/color that moves from the center of the chest out to the ends of the arms and legs.

I know they’re big goals for a beginner, but I’m starting with small steps (like how to get half a dozen LEDs doing their own things, at the same time, on the same strip). I’m also treating the whole thing like a hobby, and not just one project. If I have something usable by Halloween, AWESOME, but willing to take it as it comes.

Thanks for your suggestions and feedback!

Over lunch I just conquered having 4 LEDS blinking their own separate color! (Which, of course, means I can do the same with any number of LEDS now) Even small victories feel good!

Now to see if I can get one of them, and then all of them, to move around a little

For wearables (especially suit-like things), I’d look at strings rather than strips—much more flexible, less fiddly wiring.
