Salutations fellow nerds.
The project requires three (3x) 3ft RGB LED strips that change to a random color once a minute.
12V*15Amp PSU aside, an Arduino makes the most sense (and is my default).
Is it more efficient (code and hardware wise) to program the strip into a 1x3 LED matrix to produce three separate color changing regions OR to set up three PMW groups to modulate a total of nine (9x) mosfets?
I'm inclined to use addressable LEDs as they would probably be more efficient in both hardware and code, but am not sure how to program the matrix (Neopixel library by default) to treat groups of LEDs as one. Ex: 60 RGB LEDs, 3x groups of 20 that behave like 3 separate LEDS.
Any code samples or suggestions are much appreciated.
