Code for How to make pixel led Sd card controller using Arduino

#include "FastLED.h" // add fastled library
#include    // add sdfat library


#define NUM_LEDS 225  // total leds  
#define DATA_PIN 7    // led data pin
CRGB leds[NUM_LEDS];

//SD chip select pin
const uint8_t chipSelect = SS; //chipSelect = 10;

SdFat sd;
SdFile file;


void setup() { 
      // Uncomment/edit one of the following lines for your leds arrangement.
      // FastLED.addLeds<TM1803, DATA_PIN, RGB>(leds, NUM_LEDS);
