Vex Addressable Led problem

Why the inline resistor ?
What does the code look like ?
have you seen the possible issues I listed here.

V5 Addressable LEDs

I do want to point out a couple of issues that will be encountered when driving the addressable LED strips from the 3wire ports. Some strips will work directly without needing to do anything about these, however, some strips may need additional logic to work reliably. The addressable LEDs (WS2812, neopixel) use 5V logic but the 3wire ports are 3.3V logic. The LED want’s to detect logic 1 at 3.6V or above according to datasheet, so really our logic levels are too low. However, some strips I’v…
