Merhabalar

Rgb ledle flasör devresi yaptım aradaki bekleme süresini potansiyometreden ayarlıyorum ama pot değerini değiştirince anlık tepki vermiyor ve bekleme süreleri bittikten sonra değeri değiştiriyor.Bekleme süresine takılmadan nasıl yapabilirim.

quote:

const int kirmizi =9;
const int yesil =10;
const int mavi =11;
int ayar;
int r,g,b;
int bekle;
void setup() {

  Serial.begin(9600);
}

void loop() {
  ayar= analogRead(A0);
  ayar=map(ayar,0,1023,0,255);
  bekle=ayar;
  Serial.println(bekle);



   for(int i=1;i<=3;i++){
    r=0;
    g=0;
    b=255;
    analogWrite(kirmizi,255-r);
    analogWrite(yesil,255-g);
    analogWrite(mavi,255-b);

    delay(bekle);
    r=0;
    g=0;
    b=0;
    analogWrite(kirmizi,255-r);
    analogWrite(yesil,255-g);
    analogWrite(mavi,255-b);

    delay(bekle);
  }

  for(int i=1;i<=3;i++){
    r=255;
    g=0;
    b=0;
    analogWrite(kirmizi,255-r);
    analogWrite(yesil,255-g);
    analogWrite(mavi,255-b);

    delay(bekle);
    r=0;
    g=0;
    b=0;
    analogWrite(kirmizi,255-r);
    analogWrite(yesil,255-g);
    analogWrite(mavi,255-b);

    delay(bekle);
  }

}

Çözüm millis fonksiyonu

https://www.arduino.cc/en/Tutorial/BlinkWithoutDelay

* Blink without Delay

Turns on and off a light emitting diode (LED) connected to a digital
pin, without using the delay() function. This means that other code
can run at the same time without being interrupted by the LED code.

The circuit:
* LED attached from pin 13 to ground.
* Note: on most Arduinos, there is already an LED on the board
that's attached to pin 13, so no hardware is needed for this example.

// constants won't change. Used here to set a pin number :
const int ledPin = 13; // the number of the LED pin

// Variables will change :
int ledState = LOW; // ledState used to set the LED

// Generally, you should use "unsigned long" for variables that hold time
// The value will quickly become too large for an int to store
unsigned long previousMillis = 0; // will store last time LED was updated

// constants won't change :
const long interval = 1000; // interval at which to blink (milliseconds)

void setup() {
// set the digital pin as output:
pinMode(ledPin, OUTPUT);
}

void loop() {
// here is where you'd put code that needs to be running all the time.

// check to see if it's time to blink the LED; that is, if the
// difference between the current time and last time you blinked
// the LED is bigger than the interval at which you want to
// blink the LED.
unsigned long currentMillis = millis();

if (currentMillis - previousMillis >= interval) {
// save the last time you blinked the LED
previousMillis = currentMillis;

// if the LED is off turn it on and vice-versa:
if (ledState == LOW) {
ledState = HIGH;
} else {
ledState = LOW;
}

// set the LED with the ledState of the variable:
digitalWrite(ledPin, ledState);
}
