As my project requires a strip of LED lights that I can individually control I decided this would be a great thing to figure out for output week.

I got ahold of these LED lights from Amazon that were not branded but would hopefully do the trick. Each had 6 pads to sauder, three on the input side and three on the output. Although using a pre-built light strip was a possibility, I wanted to control the number of lights and their spacing - for the watch mode I really needed 12 lights specifically.

The process began with saudering hte lights togetherwhich was really diffuclt. After a couple of lights I realized that I could use the attached wire strings to simplify the process.

                            
                                void rainbow() {
                                    strip.clear(); // Set all pixel colors to 'off'
                                  
                                    // The first NeoPixel in a strand is #0, second is 1, all the way up
                                    // to the count of strip minus one.
                                    for(int i=0; i<12; i++) {
                                      strip.setPixelColor(i, strip.Color(0, 150, 0));
                                  
                                      strip.show();  
                                  
                                      delay(500); 
                                    }
                                  }
                                  
                                  uint32_t Wheel(byte WheelPos) {
                                    WheelPos = 255 - WheelPos;
                                    if (WheelPos < 85) {
                                      return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3);
                                    } else if (WheelPos < 170) {
                                      WheelPos -= 85;
                                      return strip.Color(0, WheelPos * 3, 255 - WheelPos * 3);
                                    } else {
                                      WheelPos -= 170;
                                      return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0);
                                    }
                                  }

void setColor(int pixel, uint32_t color) {
  strip.setPixelColor(pixel, color);
  strip.show();
}
