Hi there! I work with ws2811 and Arduino UNO now. I’ve done BT communication between Arduino UNO and my android phone and now I can manage my ws2811 led strip. Next step i want remake “Five Elements” sculpture with BT support. Can you help me with code for “Five Elements” and led strip installation in the light box? Mark Kriegsman’s comments welcome). Thank you in advance!

Hello.Do you have an example?)
Hi and welcome!
I’ll try to put together that animation code and share it here. As you may have seen, we’ve been working hard on the new library version, but I should be able to dig this up.
If I recall, that’s an LPD6803 strip with 150 LEDs grouped into 50 addressable groups of 3 each. So while there are 150 SMD LED packages, it is programmed with “NUM_LEDS” = 50.
The code is quite old and I’m sure it’ll be embarrassing for me to look at it, but I’ll be brave and share what I can.
Thanks for answer Mark! And can i use ws2811/2812 led strip for “Five Elements” effects? I’ll be wait for your code.
That fire effect is epic!
are the inner leds on some sort of tube?
Mark said that is 150 led strip cut in 3 pcs by 50 led. It is 50x3 matrix.
Actually it’s 50-“pixel” strip, just that each “pixel” is actually three SMD5050 packages in a row.
On modern strips, you can address each LED package separately. On this older model, every three LED packages were all programmed together.
Nevertheless, NUM_LEDS = 50, and everything else should work.
idk if it was a 50*3 because i know those lights and they are one chip every three so idk lol
id really like to replicate the fire effect in a sandblasted plexi tube but where do i even start??
See “Fire2012” source code here: http://pastebin.com/xYEpxqgq
The entire Fire2012 sketch is 150 lines, and compiles to 3,968 bytes. The heart of the simulation is under thirty lines, and is easy to tinker with.
thank you this is awesome thanks again
When you get it up and running, please share videos or photos!
this code is incredibly well done and works great i would never be able to replicate it thanks
Nice @Mark_Kriegsman . Thanks for sharing the Fire2012 code too!
