Ok. So this more complicated than I was thinking.
It's not really complicated. It just takes a lot of time.
My thinking was going this way(sorry if this will looks ridiculous, but I'm not yet on this level). Using this part of code.
#define BUTTON_PIN 2
#define PIXEL_PIN 6 // Digital IO pin connected to the NeoPixels.
#define PIXEL_COUNT 16 // Number of NeoPixels
// Declare our NeoPixel strip object:
Adafruit_NeoPixel strip(PIXEL_COUNT, PIXEL_PIN, NEO_GRB + NEO_KHZ800);
// Argument 1 = Number of pixels in NeoPixel strip
// Argument 2 = Arduino pin number (most are valid)
// Argument 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)
// NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products)
boolean oldState = HIGH;
int mode = 0; // Currently-active animation mode, 0-9
void setup() {
pinMode(BUTTON_PIN, INPUT_PULLUP);
strip.begin(); // Initialize NeoPixel strip object (REQUIRED)
strip.show(); // Initialize all pixels to 'off'
}
void loop() {
// Get current button state.
boolean 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) { // Yes, still low
if(++mode > 8) mode = 0; // Advance to next mode, wrap around after #8
switch(mode) { // Start the new animation...
case 0:
colorWipe(strip.Color( 0, 0, 0), 50); // Black/off
break;
case 1:
colorWipe(strip.Color(255, 0, 0), 50); // Red
break;
case 2:
colorWipe(strip.Color( 0, 255, 0), 50); // Green
break;
case 3:
colorWipe(strip.Color( 0, 0, 255), 50); // Blue
break;
case 4:
theaterChase(strip.Color(127, 127, 127), 50); // White
break;
case 5:
theaterChase(strip.Color(127, 0, 0), 50); // Red
break;
case 6:
theaterChase(strip.Color( 0, 0, 127), 50); // Blue
break;
case 7:
rainbow(10);
break;
case 8:
theaterChaseRainbow(50);
break;
}
}
}
// Set the last-read button state to the old state.
oldState = newState;
}
And.......
Sorry again brackets. I mess up again.
Mmmmm. No need to post entire sketch at this point. Take one simple effect and try to convert it.
However, now your main sketch will need to keep a variable to indicate which effect is supposed to be running...
I used states for that, like:
void displayUpdate() {
static unsigned long updateMillis;
// 20 Hz display frame rate
nowMillis = millis();
if (nowMillis - updateMillis >= 50)
{
switch (effectState) {
case NONE :
noEffect();
break;
case BIKINI :
pinkAndPurplePolkaDottedBikini();
break;
case RGB_STRIPE :
shiftRGBStripe(1);
break;
}
FastLED.show();
updateMillis = nowMillis;
}
}

I did couple posts above. But now I can't. Don't know why.
#define BUTTON_PIN 2
#define PIXEL_PIN 6 // Digital IO pin connected to the NeoPixels.
#define PIXEL_COUNT 16 // Number of NeoPixels
// Declare our NeoPixel strip object:
Adafruit_NeoPixel strip(PIXEL_COUNT, PIXEL_PIN, NEO_GRB + NEO_KHZ800);
boolean oldState = HIGH;
int mode = 0; // Currently-active animation mode, 0-9
void setup() {
pinMode(BUTTON_PIN, INPUT_PULLUP);
strip.begin(); // Initialize NeoPixel strip object (REQUIRED)
strip.show(); // Initialize all pixels to 'off'
}
void loop() {
// Get current button state.
boolean 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) { // Yes, still low
if(++mode > 8) mode = 0; // Advance to next mode, wrap around after #8
switch(mode) { // Start the new animation...
case 0:
colorWipe(strip.Color( 0, 0, 0), 50); // Black/off
break;
case 1:
colorWipe(strip.Color(255, 0, 0), 50); // Red
break;
case 2:
So this is a where button is operate.
You will have to decouple the button code and the display code. They can not be intertwined like that. Your main loop should look like:
void loop() {
readButton();
displayUpdate();
}
I'm trying do this correctly. Sorry. But on phone is complicated a bit.
So back what I would like to do.
That part of code above I'll try to join with this ..........
#define DATA_PIN 3
//#define CLK_PIN 4
#define LED_TYPE WS2811
#define COLOR_ORDER GRB
#define NUM_LEDS 64
CRGB leds[NUM_LEDS];
#define BRIGHTNESS 96
#define FRAMES_PER_SECOND 120
void setup() {
delay(3000); // 3 second delay for recovery
// tell FastLED about the LED strip configuration
FastLED.addLeds<LED_TYPE,DATA_PIN,COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip);
//FastLED.addLeds<LED_TYPE,DATA_PIN,CLK_PIN,COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip);
// set master brightness control
FastLED.setBrightness(BRIGHTNESS);
}
// List of patterns to cycle through. Each is defined as a separate function below.
typedef void (*SimplePatternList[])();
SimplePatternList gPatterns = { rainbow, rainbowWithGlitter, confetti, sinelon, juggle, bpm };
uint8_t gCurrentPatternNumber = 0; // Index number of which pattern is current
uint8_t gHue = 0; // rotating "base color" used by many of the patterns
void loop()
{
// Call the current pattern function once, updating the 'leds' array
gPatterns[gCurrentPatternNumber]();
// send the 'leds' array out to the actual LED strip
FastLED.show();
// insert a delay to keep the framerate modest
FastLED.delay(1000/FRAMES_PER_SECOND);
// do some periodic updates
EVERY_N_MILLISECONDS( 20 ) { gHue++; } // slowly cycle the "base color" through the rainbow
EVERY_N_SECONDS( 10 ) { nextPattern(); } // change patterns periodically
}
#define ARRAY_SIZE(A) (sizeof(A) / sizeof((A)[0]))
void nextPattern()
{
// add one to the current pattern number, and wrap around at the end
gCurrentPatternNumber = (gCurrentPatternNumber + 1) % ARRAY_SIZE( gPatterns);
}
void rainbow()
{
I suggest you post later from a computer. Your posts are getting truncated, cut off...

But this is original code from NeoPixel examples.
So?
Ok. Sorry.
It's okay for now. Nothing you posted will work, anyway...

Ok . Maybe tomorrow. Thanks anyway aarg.
Both codes works but little bit different like i would.

Hi aarg. This is the code I was thinking to adapt to button.
First of all, is it tested?
Yes. It works perfectly. All animations change every couple of seconds. So if I think I understant this .In loop I will put milis which you sugest me yesterday.
void displayUpdate() {
static unsigned long updateMillis;
// 20 Hz display frame rate
nowMillis = millis();
if (nowMillis - updateMillis >= 50)
{
switch (effectState) {
case NONE :
noEffect();
break;
case BIKINI :
pinkAndPurplePolkaDottedBikini();
break;
case RGB_STRIPE :
shiftRGBStripe(1);
break;
}
FastLED.show();
updateMillis = nowMillis;
}
}
than i will define button on beginnig of the sketch . And should working??
