Hello everybody. i’m working on a xmas tree project. I’m planing to use an arduino uno that i already own, or teensy 3.1 (if delevired on time), and fastled. I’d like to make an animated star with a 144pixels/m WS2812B led strip like this one : http://www.aliexpress.com/item/144-LEDs-M-WS2812B-Chip-Black-PCB-WS2811-IC-Digital-5050-RGB-LED-Strip-Light-5V/1552767923.html. I’m thinking of using only 60 out of the 144 dots for the star illumination. Then 2x50 dots WS2811 LED pixel strings like this one : http://www.aliexpress.com/item/12mm-WS2811-as-WS2801-led-pixel-module-IP68-waterproof-DC5V-full-color-RGB-50pcs-a-string/1022672558.html. Could someone tell me if it’s possible to share the same Clock / Data lines with the 2 different strips. Both seems to be using the 3 wires design so it should all be WS2812B isn’t it ? Will I need to add a resistor on the CS line like explained for the better SPI devices tutorial here : http://hackaday.com/2014/11/25/better-spi-bus-design/.
I’m a bit confused about the desription of the 50 dots LED string. WS2801 controller, but the first line says WS2812B then WS2811…
I know WS2812B is now replaced by the APA102 design but as of now it seems it’s way more expensive thant the WS2812B and i couldn’t find the 50 dots LED pixels with the APA102
I’m a noob in the arduino / microcontroller world. Any help and clues would be greatly appreciated.
