Comments: Addressable LED Neon Flex Rope Hookup Guide

Cool. Thanks for the share! =)

Other than setting up the FastLED example code for UCS1903 chip, you would tell each LED to light up green. Here's an example from the modified blink sketch. I have not tested this code but it should compile and work for the LED Neon Flex Rope.

/*Modified FastLED Blink.ino Example

   Description: This modified example is used to control one segment
       of the LED Neon Flex Rope.
*/
#include "FastLED.h"

// How many leds in your strip?
#define NUM_LEDS 16 //# of segments on the LED Neon Flex Rope

// For led chips like Neopixels, which have a data line, ground, and power, you just
// need to define DATA_PIN.  For led chipsets that are SPI based (four wires - data, clock,
// ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN
#define DATA_PIN 5
//#define CLOCK_PIN 13

// Define the array of leds
CRGB leds[NUM_LEDS];

void setup() {
  // put your setup code here, to run once:
  FastLED.addLeds<UCS1903, DATA_PIN, BRG>(leds, NUM_LEDS);

}

void loop() {
  // put your main code here, to run repeatedly:

  for (int i = 0; i > 16; i++) {
    leds[i] = CRGB::Green;
    FastLED.show();
    //delay(500);//optional delay
  }
}

There's more than one shade of green in the FastLED library. Try checking their keywords for the different greens that can be mixed together => [ https://github.com/FastLED/FastLED/blob/fece62ec8001b6aa75903cfabb4da51f59e004bd/keywords.txt#L147 ]. =)
