Hello community, I am a user of FastLED and addressible LED from Taiwan.

I am a friend of APA company in Taiwan because I use their apa102 5050 and 2020 in my poi project, I think the company is the original of those controller-integrated-3/4wire-LED, like apa102. Recenly I just had some talk and the co-owned and he gave me a lot of samples of their new package 1515, more than I can test.
I think it is a good idea to share with more people who are good at using those, so I am asking here.

Any friend here is using with apa102 want some samples of 1515 package?
the specific part is APA-102-1515-256-6
1515 means 1.5mm*1.5mm in dimensions, probably the smallest of apa102 LED.
not sure what 256 refers too, but it is the one with no flickering when global brightness is 31. and 8192 one has flickers bad with POV.
6 means it has 6 pads, better footprint for layout. some had 8 pads and not easy for layouts.

this is the reference datasheet from their web.

p.s if this in any case against the community rules please warn me, thanks

What is the best way to waterproof the 3-pin connectors between WS2811 strips? I'm planning to use a CableGuard box for the controller, but I need to waterproof the connectors in between each of my 6 strips. I'd like to not hot glue them, as I want to be able to re-use them individually.

hoping someone can point me in the right direction here. how do you do the math necessary to display something like this on a led matrix? if it was just a simple string of leds, i could see how to do it, but not for a matrix. im rather confused by this seemingly simple thought that i cant seem to find an answer to

hello please help... how to add fastled in to proteus simulator.... thank you very much

Hi folks,

I'm very new to FastLED and Arduino, but I have a few questions I'm struggling with for a project I'm working on.

Is it possible to create palettes and gradient palettes at runtime? All the examples and documentation I'm seeing has these being setup with a define statement.

Similarly, is there an easy way to set the LED type at runtime? With FastLED using different syntax depending on the LED type I suspect I'm going to have to create a function to call the appropriate command to add the LEDs for each set.

What I'm trying to do is hard code as little as possible so my controllers can use multiple types of LED, various LED string lengths, and user defined palettes, but it seems this isn't straightforward in FastLED.

Wonder what they are using for this? I used App Inventor to make a simple BLE app for the esp32 but I don't see a lot of FastLED projects that use apps and no real open source app projects to make it easy for others to control their FastLED projects.

Looks like WorldSemi is upgrading WS2812 again, without changing the model number, again. This time with integrated filter capacitors, reverse polarity protection, over-voltage protection, and 3.3V logic compatibility! I'm looking forward to getting ahold of some of these. They mention in the post that their stock of the current version will likely keep shipping for about a year, though.

I've done a few projects in the past with led strips and the Teensy 3.2/OctoWS2811 shield with FastLED. I'm thinking of doing something larger and more complex, but not sure the right direction. Something modular and wireless, but each module is controlled via a single master controller, or interface.

Take an example of 2 independent (or more) light displays that are identical. Each has their own controller with identical code and can work independently, with various patterns. Now throw in a wireless option that can control both of them and sync them. So if you choose pattern 1, it will change to pattern 1 on both and run both in sync. Or, be able to trigger running pattern 1 on display 1 and pattern 2 on display 2 at the same time, etc.

It would also be great to somehow upload new patterns to the wireless units without reprogramming them. More of a plugin kind of thing, dynamically loading them like from a text file. Is that possible?


Is anyone aware of a shared project that has a "ripple effect?"

I uncovered this thread:

That seems like a great place to start, but was curious if there was some other gold standard ripple effect code I should know about.

Thanks in advance!
