what is matter with this cod
I want to do the strip show wen I push the Butten an then end the strip show
who can help me:(((
#include “FastLED.h”
#define NUM_LEDS 11
CRGB leds[NUM_LEDS];
#define PIN D9
#define buttonPin D2
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
void setup()
{
FastLED.addLeds<WS2811, PIN, GRB>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
pinMode(buttonPin, INPUT);
}
void loop() {
buttonState = digitalRead(buttonPin);
// compare the buttonState to its previous state
if (buttonState != lastButtonState) {
// if the state has changed, increment the counter
if (buttonState == HIGH) {
// if the current state is HIGH then the button went from off to on:
buttonPushCounter++;
Serial.println(“on”);
Serial.print(“number of button pushes: “);
Serial.println(buttonPushCounter);
} else {
// if the current state is LOW then the button went from on to off:
Serial.println(“off”);
}
// Delay a little bit to avoid bouncing
delay(50);
}
// save the current state as the last state, for next time through the loop
lastButtonState = buttonState;
}
colorWipe(0xff,0x00,0x00, 50);
colorWipe(0x00,0x00,0x00, 50);
}
void colorWipe(byte red, byte green, byte blue, int SpeedDelay) {
for(int i=NUM_LEDS; i>=0; i– ) {
if (buttonPushCounter % 4 == 0){
setPixel(i, red, green, blue);
showStrip();
delay(SpeedDelay);
}
}
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
}
Since you're using FastLED, I'd focus on that an remove irrelevant code from AdaFruit (like setPixel and shwoStrip).
This will shorten the code a little.
I've modified your code a little but I have not been able to test the code (don't have my Arduino near me).
Hope this helps
