Add 0-99 counter buttons help

Using Arduino Programming Questions
1

I designed the 0-FF counter but now I need to cancel this automatic counting and increase it with a button instead of it I programmed the program with 7 digital outputs to check the displays and check the cathodes of the digital input displays in the button and I count the counter from 0 to FF, I can not find my attachment, can I help?

const int a = 2;
const int b = 3;
const int c = 4;

const int f = 7;
const int g = 8;
const int dp = 9;
const int konlar = 10;
const int kbirler = 11;
const int but = 12;
int sayici;

void setup() {
for (int i = 2; i < 16; i++)
{ //delay(100);
pinMode(i, OUTPUT);
}
pinMode(but, INPUT_PULLUP);
sayici = 0;
}

void loop() {
int birler = sayici % 16;
int onlar = sayici / 16;
int i = 0;
while (i < 35)
{
goster(birler);
digitalWrite(kbirler, HIGH);
digitalWrite(konlar, LOW);
delay(10);
goster(onlar);
digitalWrite(kbirler, LOW);
digitalWrite(konlar, HIGH);
delay(10);
i++;

sayici = 0;

Hello, necoli35. Welcome to the Arduino forum.

When posting code, please remember to use code tags. If you don't know what code tags are, please look here: How to use this forum - please read - Website and Forum - Arduino Forum and read number 7.

I noticed this in your loop:

  sayici++;

That will make the counter go up, always.
But, you do not always want the counter to go up. You want it to depend on the button.
I noticed that you are using INPUT_PULLUP. Here is what I read about INPUT_PULLUP:

When connecting a sensor to a pin configured with INPUT_PULLUP, the other end should be connected to ground. In the case of a simple switch, this causes the pin to read HIGH when the switch is open, and LOW when the switch is pressed.

I got that information from here: https://www.arduino.cc/en/Tutorial/DigitalPins
So, we know that if the pin reads LOW, then the button is being pressed. Here is how we use that knowledge:

  if (digitalRead(but)==LOW) {
    sayici++;
  }

That way, the counter will go up when, and only when, you hold down the button.
Please try this and tell us what happens.
