Marc, thank you for your time. I still don’t see the light. I know this light strip has 30 LEDs, 3 sets of 10. that’s why I tried 30 and 10 and I tried green wire in 3 and 11.
I’ll send pics of my setup in a while.
I included an LED on my board to ensure i was getting voltage in the right direction.
How can tell if the program is finding:
#include “FastLED.h”
Where would I look on my computer to see if it copied to the right directory?
I tried:
#define NUM_LEDS 10
#define NUM_LEDS 30
#define DATA_PIN 11
#define DATA_PIN 3
Here is my code:
// Use if you want to force the software SPI subsystem to be used for some reason (generally, you don't)
// #define FASTLED_FORCE_SOFTWARE_SPI
// Use if you want to force non-accelerated pin access (hint: you really don't, it breaks lots of things)
// #define FASTLED_FORCE_SOFTWARE_SPI
// #define FASTLED_FORCE_SOFTWARE_PINS
#include "FastLED.h"

// Move a white dot along the strip of leds. This program simply shows how to configure the leds,
// and then how to turn a single pixel white and then off, moving down the line of pixels.
//
// How many leds are in the strip?
#define NUM_LEDS 10
// Data pin that led data will be written out over
#define DATA_PIN 11
// Clock pin only needed for SPI based chipsets when not using hardware SPI
//#define CLOCK_PIN 8
// This is an array of leds. One item for each led in your strip.
CRGB leds[NUM_LEDS];
// This function sets up the ledsand tells the controller about them
void setup() {
// sanity check delay - allows reprogramming if accidently blowing power w/leds
delay(2000);
// Uncomment one of the following lines for your leds arrangement.
