Hi,

I’m pretty new to this stuff. I’m trying to build a controller using Teensy 3.1 and the FastLED library under Teensy Arduino to control this LED strip: http://www.lightingnext.com/1m-96-ws2812b-neopixel-strip.html and this is the data sheet: http://www.lightingnext.com/WS2812B.pdf

I’ve started with the Blink example, hoping to just blink the first LED, but I’m having no luck. The board works fine, and I’ve got the data line attached to Teensy 3.1’s pin 11. I’ve got the following line uncommented in the setup:

  FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);

and set DATA_PIN to 11. All I get is a solid blue light on all of the LEDs on the strip. If I change the data pin to 13 (the on-board LED), that LED flashes as expected.

Any idea where I’m going wrong? I’m sort of stumped at this point.

Thanks in advance for any help.

I will attach photos with power on and off for my setup to a follow-up post …

Should I be using a different pin on the board? Or specifying a different pin number to FAST_LED?

Thanks Dave. I already knew that. My using the Blink example was just to try to figure out what was wrong with my setup. As I’ve said, I’ve already figured that out (I had hooked up to the wrong end of the strip - I’m and idiot). It’s now all working properly using the FastLED libraries as they are intended to be used.

ok gotcha. haha hey I didn’t know

And there’s nothing ‘discount’ about that companies prices for WS2812B… 60/M should be about $11-15, 144/M are about $25.
