user50490: I have an Arduino Uno and a string of WS2811 LEDs. I am still trying to get started on this project, which is creating a Stranger Things wall. I've installed FastLED and uploaded the sample program "Blink" to the Arduino, which appears to upload correctly. However, the lights don't blink.
Notes:
 - When I plug the string of lights into a power source (when disconnected from the Arduino), they briefly light up red and then turn off. I don't know if this means there's something wrong with the power setup. (I don't know if they are supposed to stay on.)
 - Here's a photo of my connection from the Arduino to the LEDs
 

Here's the setup I'm trying to follow.


Thanks in advance for any help!

user50490: The sample code sets the data pin to 3, but I was using 6. Noob mistake.
