i need some help for my masterthesis. I plan an Light and Sound installation and for this I decided to use the shape of an Dodecahedron and I want to put LED RGB Pixel Stripes on the surfaces to light the space. Imagine it like a huge ceiling light in shape of a half Dodecahedron.

What I have:

  • 1 x Arduino Starter Kit
  • 4 x RGB LED Pixel Stripe: BTF-LIGHTING WS2811, 5M, 60 LEDs/m, 300LEDs RGB, DC12V
    • (0,3W/LED = 90W/5 M (1 LED Stripe) = 360 W/20 M an in total 40A (4 LED Stripes))
  • 2 x LED Stripe: Minger SMD 2835, 5m, 300 LEDs, Dimmable, 6000K Kaltweiß, DC12V (?)

The half of the Dodecahedron has 6 surfaces. Each surface gets like 300 to 350 cm RGB LEDs and 150 cm of Cold White.

My plan is to program the RGB LEDs with Strobe-Light (10 Hz) and changing colours and at the End of the installation the Cold White ("Daylight") is lighten up the space. (But this is another challenge for me ;))

How to connect all of them with my Arduino Uno? Any ideas? Thank you very much!

So, addressable RGB LED strips. You can drive each string from an Arduino output, or daisy chain the signal thru all of them and just pump out the needed data using Adafruit Neopixel library, or the FastLED library. Make multiple power connections to keep the amount of 12V current going thru any one strip to a reasonable level.
