groundFungus:
This Adafruit tutorial may be of interest.
Thank you so much for this. I was looking for the wrong terminology all along.
I've managed to change some code around mixing and matching from various other codes and experimenting with variables and what nots. The code is near finished for what I would like to do. However I could use some assistance with changing an int to a variable number that is defined by a pot.
I would like to make the speed adjustable. the problem lies that i have included the speed in each of the routines.
Another item i will eventually incorporate is a brightness pot.
lastly I would like to separate the 2 types of sequences by using a switch. but that is a luxury not a necessity.
here is my code.
#include <Adafruit_NeoPixel.h>
#include <EEPROM.h>
#define BRIGHTNESS 60
#define NUM_LEDS 21
#define PIN 6
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, PIN, NEO_GRBW + NEO_KHZ800);
#define BUTTON 2
byte selectedEffect=0;
void setup()
{
strip.begin();
strip.show(); // Initialize all pixels to 'off'
digitalWrite (BUTTON, HIGH); // internal pull-up resistor
attachInterrupt (digitalPinToInterrupt (BUTTON), changeEffect, CHANGE); // pressed
strip.setBrightness(BRIGHTNESS);
}
// *** REPLACE FROM HERE ***
void loop() {
EEPROM.get(0,selectedEffect);
if(selectedEffect>8) {
selectedEffect=0;
EEPROM.put(0,0);
}
switch(selectedEffect) {
case 1 : {
// CylonBounce - Color (red, green, blue, white), eye size, speed delay, end pause
CylonBounce(255, 0, 0, 0, 1, 50, 0);
break;
}
case 2 : {
// CylonBounce - Color (red, green, blue, white), eye size, speed delay, end pause
CylonBounce(0, 255, 0, 0, 1, 50, 0);
break;
}
case 3 : {
// CylonBounce - Color (red, green, blue, white), eye size, speed delay, end pause
CylonBounce(0, 0, 255, 0, 1, 50, 0);
break;
}
case 4 : {
// CylonBounce - Color (red, green, blue, white), eye size, speed delay, end pause
CylonBounce(0, 0, 0, 255, 1, 50, 0);
break;
}
case 5 : {
// NewKITT - Color (red, green, blue, white), eye size, speed delay, end pause
NewKITT(255, 0, 0, 0, 1, 50, 0);
break;
}
case 6 : {
// NewKITT - Color (red, green, blue, white), eye size, speed delay, end pause
NewKITT(0, 255, 0, 0, 1, 50, 0);
break;
}
case 7 : {
// NewKITT - Color (red, green, blue, white), eye size, speed delay, end pause
NewKITT(0, 0, 255, 0, 1, 50, 0);
break;
}

NewKITT(0, 0, 0, 255, 1, 50, 0);
break;
}
}
}
void changeEffect() {
if (digitalRead (BUTTON) == HIGH) {
selectedEffect++;
EEPROM.put(0, selectedEffect);
asm volatile (" jmp 0");
