Trying to do code for Running Lights on Neopixel with Arduino

Hi all!

I've been trying to do the code for the Running Lights effect on my neopixel lights. I've tried to copy the code from the LEDStrip Effects into the Framework, no go. I've tried to also run the zip file that is posted to download and Arduino IDE won't build it. Here I have attached the code I have been working with and the simulator I am using says it's a bad build. (Yes I am a newbie to this stuff but come on, simple cut and paste from the forum topic right?) Any and all help would be great!

#include <Adafruit_NeoPixel.h>
#define PIN 6
#define NUM_LEDS 60
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// 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(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}

//  REPLACE FROM HERE 
void loop() {
  RunningLights(0xff,0,0, 50);        // red
  RunningLights(0xff,0xff,0xff, 50);  // white
  RunningLights(0,0,0xff, 50);        // blue
}

void loop() {
  RunningLights(0xff,0xff,0x00, 50);
}

void RunningLights(byte red, byte green, byte blue, int WaveDelay) {
  int Position=0;
 
  for(int j=0; j<NUM_LEDS*2; j++)
  {
      Position++; // = 0; //Position + Rate;
      for(int i=0; i<NUM_LEDS; i++) {
        // sine wave, 3 offset waves make a rainbow!
        //float level = sin(i+Position) * 127 + 128;
        //setPixel(i,level,0,0);
        //float level = sin(i+Position) * 127 + 128;
        setPixel(i,((sin(i+Position) * 127 + 128)/255)*red,
                   ((sin(i+Position) * 127 + 128)/255)*green,
                   ((sin(i+Position) * 127 + 128)/255)*blue);
      }
     
      showStrip();
      delay(WaveDelay);
  }
}

// ---> here we define the effect function <---
//  REPLACE TO HERE 

void showStrip() {
 #ifdef ADAFRUIT_NEOPIXEL_H 
   // NeoPixel
   strip.show();
 #endif
 #ifndef ADAFRUIT_NEOPIXEL_H
   // FastLED
   FastLED.show();
 #endif
}

void setPixel(int Pixel, byte red, byte green, byte blue) {
 #ifdef ADAFRUIT_NEOPIXEL_H 
   // NeoPixel
   strip.setPixelColor(Pixel, strip.Color(red, green, blue));
 #endif
 #ifndef ADAFRUIT_NEOPIXEL_H 
   // FastLED
   leds[Pixel].r = red;
   leds[Pixel].g = green;
   leds[Pixel].b = blue;
 #endif
}

void setAll(byte red, byte green, byte blue) {
  for(int i = 0; i < NUM_LEDS; i++ ) {
    setPixel(i, red, green, blue); 
  }
  showStrip();
}

Don't worry, we all have been newbies at some point 😉 

Alright first of all, when you see an error: always make it a habit to copy and paste the exact error message.
I've never seen a "bad build" error message, and I highly doubt this error even exists - so I cannot even guess what this means.

Next: each Arduino sketch has only one "void setup()" and only one "void loop()". 
If you define this function twice, like in your code, the Arduino/Compiler will not know which one to pick.

Tip: I know this may be too much reading, but I did write a little intro for Arduino programming which also shows some of the basics of the C language.

Tip: Also make sure that you have the AdaFruit library installed (Arduino IDE: Tools -> Manage Libraries).

So, your code corrected (merging both "void loop()" sections):

#include <Adafruit_NeoPixel.h>
#define PIN 6
#define NUM_LEDS 60
// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// 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(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  strip.begin();
  strip.show(); // Initialize all pixels to 'off'
}

//  REPLACE FROM HERE 
void loop() {
  RunningLights(0xff,0,0, 50);        // red
  RunningLights(0xff,0xff,0xff, 50);  // white
  RunningLights(0,0,0xff, 50);        // blue

  RunningLights(0xff,0xff,0x00, 50);
}

void RunningLights(byte red, byte green, byte blue, int WaveDelay) {
  int Position=0;
 
  for(int j=0; j<NUM_LEDS*2; j++)
  {
      Position++; // = 0; //Position + Rate;
      for(int i=0; i<NUM_LEDS; i++) {
        // sine wave, 3 offset waves make a rainbow!
        //float level = sin(i+Position) * 127 + 128;
        //setPixel(i,level,0,0);
        //float level = sin(i+Position) * 127 + 128;
        setPixel(i,((sin(i+Position) * 127 + 128)/255)*red,
                   ((sin(i+Position) * 127 + 128)/255)*green,
                   ((sin(i+Position) * 127 + 128)/255)*blue);
      }
     
      showStrip();
      delay(WaveDelay);
  }
}

// ---> here we define the effect function <---
//  REPLACE TO HERE 

void showStrip() {
 #ifdef ADAFRUIT_NEOPIXEL_H 
   // NeoPixel
   strip.show();
 #endif
 #ifndef ADAFRUIT_NEOPIXEL_H
   // FastLED
   FastLED.show();
 #endif
}

void setPixel(int Pixel, byte red, byte green, byte blue) {
 #ifdef ADAFRUIT_NEOPIXEL_H 
   // NeoPixel
   strip.setPixelColor(Pixel, strip.Color(red, green, blue));
 #endif
 #ifndef ADAFRUIT_NEOPIXEL_H 
   // FastLED
   leds[Pixel].r = red;
   leds[Pixel].g = green;
   leds[Pixel].b = blue;
 #endif
}

void setAll(byte red, byte green, byte blue) {
  for(int i = 0; i < NUM_LEDS; i++ ) {
    setPixel(i, red, green, blue); 
  }
  showStrip();
}

Ok cool. I thought I had everything up to snuff so to speak. Can you coach me how to do a random light pattern? Like the colors are chasing each other? (Like I said, total newb here)

Also... the extra loop and setup was by using the code from your forum with all of the effects :D

I can try to help 😊 

What do you mean with random light pattern? I'm not sure what you mean with colors chasing each other. (sorry 😉)
