Try this example:

FastLED/FastLED/blob/master/examples/Blink/Blink.ino

#include <FastLED.h>

// How many leds in your strip?
#define NUM_LEDS 1

// For led chips like WS2812, 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
// Clock pin only needed for SPI based chipsets when not using hardware SPI
#define DATA_PIN 3
#define CLOCK_PIN 13

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

void setup() { 
    // Uncomment/edit one of the following lines for your leds arrangement.
    // ## Clockless types ##
    FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);  // GRB ordering is assumed
    // FastLED.addLeds<SM16703, DATA_PIN, RGB>(leds, NUM_LEDS);
