1 Button & 6 Neopixel Strips for an Explorers Map

Here is what I am attempting to make....

An interactive display where a user pushes a single button and 1 of the 6 strips lights in a slow sequence, showing the path an explorer took from point a to point b.

There are 6 paths, each path will be its own neopixel strip. When the button is pressed a second time, the first strip goes off and the second strip sequentially lights, all the way through the 6 strips, ending at all strips off.

I'd like to make the code work so I can use 6 PMW pins as wiring these as one large array is not practical, possible, just not practical.

I am using the following:
- 1 Arduino Mega 2560,
- 1 momentary push button, and
- 6 5v neopixel strips (currently with 19 pixels each, end product will be 60 each.
- Windows PC and USB to power for testing

I am attaching a code that works great with the button pushes for a single strip, and have a different color applied to each "case" so I'd know which one was active.
Is a variable for the output pin number IE 3,4,5,6,7,8 the best way, or do I require a different type of condition?
Thank you for any help here!

// This is a demonstration on how to use an input device to trigger changes on your neo pixels.
// You should wire a momentary push button to connect from ground to a digital IO pin.  When you
// press the button it will change to a new pixel animation.  Note that you need to press the
// button once to start the first animation!

#include <Adafruit_NeoPixel.h>

#define BUTTON_PIN   3    // Digital IO pin connected to the button.  This will be
                          // driven with a pull-up resistor so the switch should
                          // pull the pin to ground momentarily.  On a high -> low
                          // transition the button press logic will execute.

#define PIXEL_PIN    6    // Digital IO pin connected to the NeoPixels.

#define PIXEL_COUNT 19

// Parameter 1 = number of pixels in strip,  neopixel stick has 8
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
//   NEO_RGB     Pixels are wired for RGB bitstream
//   NEO_GRB     Pixels are wired for GRB bitstream, correct for neopixel stick
//   NEO_KHZ400  400 KHz bitstream (e.g. FLORA pixels)
//   NEO_KHZ800  800 KHz bitstream (e.g. High Density LED strip), correct for neopixel stick
Adafruit_NeoPixel strip = Adafruit_NeoPixel(PIXEL_COUNT, PIXEL_PIN, NEO_GRB + NEO_KHZ800);

bool oldState = HIGH;
int showType = 0;

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

void loop() {
  // Get current button state.
  bool newState = digitalRead(BUTTON_PIN);
 
  // Check if state changed from high to low (button press).
  if (newState == LOW && oldState == HIGH) {
    // Short delay to debounce button.
    delay(20);
    // Check if button is still low after debounce.
    newState = digitalRead(BUTTON_PIN);
    if (newState == LOW) {
      showType++;
      if (showType > 6)
        showType=0;
      startShow(showType);
    }
  }

  // Set the last button state to the old state.
  oldState = newState;
}

void startShow(int i) {
  switch(i){
    case 0: colorWipe(strip.Color(0, 0, 0), 0);    // Black/off
            break;
    case 1: colorWipe(strip.Color(255, 0, 0), 100);  // Red
            break;
    case 2: colorWipe(strip.Color(0, 255, 0), 100);  // Green
            break;
    case 3: colorWipe(strip.Color(0, 0, 255), 100);  // Blue
            break;
    case 4: colorWipe(strip.Color(127,127,127), 100);  // White
            break;
    case 5: colorWipe(strip.Color(255, 0, 0), 100);  // Red
            break;
    case 6: colorWipe(strip.Color(0, 0, 255), 100);  // Blue
            break;
  }
}

// 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);
  }
}

I'd personally prefer to wire them in one or two strings, but its your project.

Create 6 different strips at the outset - you can see how the code you've copied created one strip. Make "strip" "strip0", "strip1","strip2" etc etc

Then the case statement is

switch(i){
case 0: {colorWipe(strip0.Color(255, 0, 0), 0); // Black/off

colorWipe(strip1,Color(0,0,0),0);

colorWipe(strip2,Color(0,0,0),0);

colorWipe(strip3,Color(0,0,0),0);

colorWipe(strip4,Color(0,0,0),0);

colorWipe(strip5,Color(0,0,0),0);

}

break;

}

Case 1:{colorWipe(strip1.Color(255, 0, 0), 0); // Black/off

colorWipe(strip0,Color(0,0,0),0);

colorWipe(strip1,Color(0,0,0),0);

colorWipe(strip2,Color(0,0,0),0);

colorWipe(strip3,Color(0,0,0),0);

colorWipe(strip4,Color(0,0,0),0);

}

break;
