Switch mode with neopixels

Need Help With My Project
1

Hello everybody, first i’m sorry for my bad english :confused:
I have an esp8266 and a led strip WS2812. I use the adafruit neopixel library.
I have an switch case with an push button for change colors mode of the strip (1. static color, 2. control with blynk “wifi”, 3. rainbow). I want to change modes too with blynk. i’ve created an push button in blynk with the digital pin of my hardware push button. I can change from static to “wifi” and from “wifi” to “rainbow” but after i can’t change with blynk push button but i can change it with hardware button. So i want to change modes with pushbutton or switch (from 1 to 3). can you help me ? This is my code :

#define BLYNK_PRINT Serial
#include <BlynkSimpleEsp8266.h>
#include <Adafruit_NeoPixel.h>
#include <ESP8266WiFi.h>

#define LED_PIN    4
#define LED_COUNT 14
#define BUTTON_LEAD  2
#define NUMBER_OF_PIXELS 56
#define NUMBER_OF_MODES 3

Adafruit_NeoPixel strip(LED_COUNT, LED_PIN, NEO_GRB + NEO_KHZ800);

char auth[] = "token";
char ssid[] = "ssid";
char pass[] = "password";

int data=255;
int r,g,b;

bool buttonState = LOW;
bool lastButtonState = LOW;

const int PIXEL_FLASH_INTERVAL = 100;
const long interval = 15;
unsigned long previousMillis = millis();

int mode = 1; 

void setup() {
  Blynk.begin(auth, ssid, pass);
  pinMode(BUTTON_LEAD, INPUT);
  strip.begin();
}

BLYNK_WRITE(V3)
{
  r = param[0].asInt();
  b = param[1].asInt();
  g = param[2].asInt();

  static1(r, g, b,data);
}


void loop() {
   Blynk.run();
      switch(mode) {           // Start the new animation...
        case 1:
          staticcolor();
          break;
        case 2:
          static1(r, g, b, data);
          break;
        case 3:
          rainbow(15);
          break;

          default:
          mode = 1;
          break;
      }
    }

BLYNK_WRITE(V2)
{
data = param.asInt(); 
static1(r, g, b,data);
}

void rainbow(int wait) {
  if(millis() - previousMillis >= PIXEL_FLASH_INTERVAL) {
      previousMillis = millis();
  }
  
  strip.setBrightness(255);
  for(long firstPixelHue = 0; firstPixelHue < 5*65536; firstPixelHue += 256) {
    for(int i=0; i<strip.numPixels(); i++) {
      int pixelHue = firstPixelHue + (i * 65536L / strip.numPixels());
      strip.setPixelColor(i, strip.gamma32(strip.ColorHSV(pixelHue)));
      
    }
    strip.show();
    if(buttonListener()) { return; }
    delay(wait);

}
}
void staticcolor() {
  
  if(millis() - previousMillis >= PIXEL_FLASH_INTERVAL) {
      previousMillis = millis();
  }
  strip.setBrightness(255);
  for(int i = 0; i < LED_COUNT; i++ ) {

    strip.setPixelColor(i, strip.Color(0, 255, 255));
    if(buttonListener()) { return; }
  }
  strip.show();
}


void static1(int r, int g, int b,int brightness)
{
  strip.setBrightness(brightness);
  for (int i = 0; i < LED_COUNT; i++ )
  {
    strip.setPixelColor(i, strip.Color(r, g, b));
    if(buttonListener()) { return; }
  }
  strip.show();
}


bool buttonListener() {
  bool modeChanged = false;

  buttonState = digitalRead(BUTTON_LEAD);

  if (buttonState != lastButtonState) {
    if (buttonState == HIGH) {
      mode++;
      modeChanged = true;
      delay(250);
    }
  }
  lastButtonState = buttonState;

  return modeChanged;
}

Try editing the code so all can read triple “back ticks” or use these ``` on the line before your code starts and the line after.

@Michou69 I fixed your code posting… backticks, not quotes, etc.

Thank You,
I’m very sorry it’s my first time when I ask for help here. :slight_smile:
