G+_John Saunders Posted November 29, 2017 Share Posted November 29, 2017 Good evening all, I've placed (and anxiously waiting) for two 16.4ft WS2812B LED strips. My idea is to place them around the outside of my 2-door garage and program them based on time, garage door open/closed, and season. However, I've searched and could not find the answer for this: Can you install the WS2812 data wire in series of the two strips, so the end of strip 1 continues to send data to strip 2? I've already planned and wired for one massive power supply to independently drive the strips, but I didn't know if the data pin was as simple as wiring in series then changing the code to include the added LEDs. Thanks in advance. Link to comment Share on other sites More sharing options...
G+_David Peach Posted November 29, 2017 Share Posted November 29, 2017 If you are talking about controlling it with an Arduino or Raspberry Pi, then yes you can daisy chain them. If you plan to control it all with the remote that may or may not come with your strips I would guess it depends on whether you are just changing them all one color or trying to run an animation. Animation probably would not work as expected using a remote from one strip to control several. Link to comment Share on other sites More sharing options...
G+_John Saunders Posted November 29, 2017 Author Share Posted November 29, 2017 My plan is to use an Arduino Uno that I happen to have a few spares roaming around my work area. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted November 30, 2017 Share Posted November 30, 2017 I've got a similar project planned. I'd like to put LED strips along the soffit on the front of my house and have lights I can leave up all year long. Make them red & green for Christmas; red, white, and blue for Independence Day; pink for Valentine's... Just need to convince my wife it's worth the $$$ spent on lights.

G+_David Ewing Posted November 30, 2017 Share Posted November 30, 2017 Two pieces of advice for the strips 1) Use the waterproof strips (IP67) for outdoor use or they probably won't last long. 2) Provide power from both ends of the strip or don't run them at 100% brightness or you will see the LEDs at the end dim towards the red color. One day I will writeup the my WS812 led strip project that involves around 2200 LEDs that go all around the end of my house. When you get that big you have to worry alot about power and use a Teensy: pjrc.com - OctoWS2811 LED Library, Driving Hundreds to Thousands of WS2811 LEDs with Teensy 3.0 Link to comment Share on other sites More sharing options...
