Arduino loop one time

Question

I want to run this for loop which on abc() function only one time. But it works continuously. What should I do?

const int buttonPin = 2;
int buttonState = 0;
int i;

void setup() {  
    pinMode(buttonPin, INPUT);
}

void abc(){
    if (buttonState == HIGH) {
        for(i=0; i<240; i++)
        {
            analogWrite(6,i);
        }

     }
     else {
         analogWrite(6,0);
     }
 }

void loop() {
    buttonState = digitalRead(buttonPin);
    abc();
}

Answer 1

You can use some boolean in IF statement, like this:

bool ABC = true;

void loop() {
    if(ABC) {
        abc();
        ABC = false;
    }
}

I hope it's help.
