Arduino and Race Coordinator(HELP NEEDED)

Using Arduino Microcontrollers

Hello
I know hardware and struggle with code.
Can someone PLEASE help !!!

Here's the changes I made. (top line is what I changed)

''' #define SETUP_LED_1(cgrb, 8) FastLED.addLeds<NEOPIXEL, STRING_PIN_1>(cgrb, 8);

#define SETUP_LED_2(leds, numLeds) FastLED.addLeds<NEOPIXEL, STRING_PIN_2>(leds, numLeds);

I swapped this "cgrb, 8", thinking it defined "LEDS" and "numLEDS". '''

Here are the instructions I'm working with.

''' // Comment in LED_TYPE_1 through LED_TYPE_4 and set them to the correct value. Then comment in

// these 4 macros, OR leave these 4 macros commented out and comment in the 4 NEOPIXEL macros

// which are basically WS2811 with the color format set to GRB.

//#define SETUP_LED_1(leds, numLeds) FastLED.addLeds<LED_TYPE_1, STRING_PIN_1, RGB>(leds, numLeds);

//#define SETUP_LED_2(leds, numLeds) FastLED.addLeds<LED_TYPE_2, STRING_PIN_2, RGB>(leds, numLeds);

//#define SETUP_LED_3(leds, numLeds) FastLED.addLeds<LED_TYPE_3, STRING_PIN_3, RGB>(leds, numLeds);

//#define SETUP_LED_4(leds, numLeds) FastLED.addLeds<LED_TYPE_4, STRING_PIN_4, RGB>(leds, numLeds);

#define SETUP_LED_1(cgrb, 8) FastLED.addLeds<NEOPIXEL, STRING_PIN_1>(cgrb, 8);

#define SETUP_LED_2(leds, numLeds) FastLED.addLeds<NEOPIXEL, STRING_PIN_2>(leds, numLeds);

#define SETUP_LED_3(leds, numLeds) FastLED.addLeds<NEOPIXEL, STRING_PIN_3>(leds, numLeds);

#define SETUP_LED_4(leds, numLeds) FastLED.addLeds<NEOPIXEL, STRING_PIN_4>(leds, numLeds); '''

The NEOPIXEL 8 Led bar works with "Example" sketches.
But the code changes are explained, so I made it through.

Been fighting various issues with the system I'm setting up.
this is the last major hurdle as far as testing configuration goes.

Once I get this I can start putting it together.

you do not appear to give the origin of the code you are changing? where did it come from?

have a read of how-to-get-the-best-out-of-this-forum

this expression appears only once in code so using #define to replace it is not smart.
