Hello,
I am building a cake topper for my wedding and I just got some Adafruit Neopixel rings to do some lighting effects but Im having a problem getting the lights to work in my program. I have the lights working in a different sketch but when I try to add it I keep getting function-definition is not allowed here before "{" token errors. Im not sure why since it is set up exactly like the file that works. Here is the code that works
#include <Adafruit_NeoPixel.h>
#define PIN 53
// Parameter 1 = 24
// Parameter 2 = PIN
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
Adafruit_NeoPixel strip = Adafruit_NeoPixel(36, PIN, NEO_GRB + NEO_KHZ800);
// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across
// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input
// and minimize distance between Arduino and first pixel. Avoid connecting
// on a live circuit...if you must, connect GND first.
void setup() {
strip.begin();
strip.show(); // Initialize all pixels to 'off'
}
void loop() {
delay(5000);
rainbow(150);
// rainbowCycle(20);
// theaterChaseRainbow(50);
}
// Fill the dots one after the other with a color
//void colorWipe(uint32_t c, uint8_t wait) {
// for(uint16_t i=0; i<strip.numPixels(); i++) {
// strip.setPixelColor(i, c);
// strip.show();
// delay(wait);
// }
//}
void rainbow(uint8_t wait) {
uint16_t i, j;
for(j=0; j<256; j++) {
for(i=0; i<strip.numPixels(); i++) {
strip.setPixelColor(i, Wheel((i+j) & 255));
}
strip.show();
delay(wait);
}
}
// Slightly different, this makes the rainbow equally distributed throughout
void rainbowCycle(uint8_t wait) {
uint16_t i, j;
for(j=0; j<256*5; j++) { // 5 cycles of all colors on wheel
for(i=0; i< strip.numPixels(); i++) {
strip.setPixelColor(i, Wheel(((i * 256 / strip.numPixels()) + j) & 255));
}
strip.show();
delay(wait);
}
}
// Input a value 0 to 255 to get a color value.
// The colours are a transition r - g - b - back to r.
uint32_t Wheel(byte WheelPos) {
if(WheelPos < 85) {
return strip.Color(WheelPos * 3, 255 - WheelPos * 3, 0);
} else if(WheelPos < 170) {
WheelPos -= 85;
return strip.Color(255 - WheelPos * 3, 0, WheelPos * 3);
} else {
WheelPos -= 170;
return strip.Color(0, WheelPos * 3, 255 - WheelPos * 3);
}
}
and this is the code I have so far that will not work.

can anyone give me a hand on this one? Thanks!
