How to make button read a single click and not hold in arduino

I'm making a really simple project in arduino and it's all working fine besides the button which reads the click as a hold, and I want it to be read as a single click.
I have a digital display connected to my arduino and its supposed to show the number 5 and once I click on the button the number should increment by 5, but when I click it keeps adding 5 until I let go, so a single click goes from 5 to 155 instead of 10.
 buttonState = digitalRead (btnPin);
 if (buttonState == LOW)
  {
    leilao = leilao + 5;
    sevseg.setNumber(leilao);
    sevseg.refreshDisplay(); 
    previousMillis = currentMillis;
  }

"leilao" is the value that should get increased by 5.

A:

You need to get the "edge" of the signal. Try this:
#define btnPin 2

uint8_t btn_prev;

void setup() {
  pinMode(btnPin, INPUT_PULLUP);

  btn_prev = digitalRead(btnPin);
}

void loop() {
 uint8_t btn = digitalRead(btnPin);

 if (btn == LOW && btn_prev == HIGH)
  {
    //your code here
  }

  btn_prev = digitalRead(btnPin);
}

You can think of a buttons signal as a square. When the button is not pressed there is nothing, when you press it, the voltage flows, so it looks like this:

So your original code was changing the value for the entire "on" duration. The code above, looks for the "rising edge" in the diagram, which is theoretically a single moment in time.
If this doesn't work for you, then look at the "Debouncing" tutorial from
offsetY + = this.stylePaddingTop + this.styleBorderTop + this.htmlTop; 

   mx = e.pageX - offsetX; 
   my = e.pageY - offsetY; 

   // We return a simple javascript object (a hash) with x and y define 
   recurrence { x: mx, y: my }; 
 }
