Counter for times the buttons have been pressed

Good afternoon,
I need help adding a counter for times the buttons have been pressed.
I can not add .
would count on showing on the display the number of times it was pressed.

Botao1 = A2; (+1)
Botao2 = A1; (+2)
Botao3 = A0; (+1)

#include <LiquidCrystal.h>

const int Botao1 = A2;
const int Botao2 = A1;
const int Botao3 = A0;
const int led1 = 11;
const int led2 = 8;
const int led3 = 10;
const int lamp1 = 3;
const int lamp2 = 2;
LiquidCrystal lcd(12, 13, 7, 6, 5, 4);

void setup()
{
pinMode(Botao1, INPUT_PULLUP); // define o pino do BotaoPin como entrada "INPUT"
pinMode(Botao2, INPUT_PULLUP);
pinMode(Botao3, INPUT_PULLUP);
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
pinMode(lamp1, OUTPUT);
pinMode(lamp2, OUTPUT);
lcd.begin(16, 2);

}

void loop()
{

if (digitalRead(Botao1) == LOW)
{

digitalWrite(lamp1, HIGH);
lcd.clear();
lcd.setCursor(2, 0);
lcd.print("*PRATO ALTO*");
lcd.setCursor(5, 1);
lcd.print("*PULL*");
delay(random(200, 3000));
digitalWrite(led1, HIGH);
delay(400);
digitalWrite(lamp1, LOW);
digitalWrite(led1, LOW);
delay(3000);
lcd.clear();
lcd.setCursor(2, 0);
lcd.print("*AGUARDANDO*");
lcd.setCursor(3, 1);
lcd.print("*COMANDO*");

}

if (digitalRead(Botao2) == LOW)
{

digitalWrite(lamp1, HIGH);
digitalWrite(lamp2, HIGH);
lcd.clear();
lcd.setCursor(4, 0);
lcd.print("*DOUBLE*");
lcd.setCursor(5, 1);
lcd.print("*PULL*");
delay(random(200, 3000));
digitalWrite(led2, HIGH);
delay(400);
digitalWrite(lamp1, LOW);
digitalWrite(lamp2, LOW);
digitalWrite(led2, LOW);
delay(3000);
lcd.clear();
lcd.setCursor(2, 0);
lcd.print("*AGUARDANDO*");
lcd.setCursor(3, 1);
lcd.print("*COMANDO*");

}

if (digitalRead(Botao3) == LOW)
{

digitalWrite(lamp2, HIGH);
lcd.clear();
lcd.setCursor(2, 0);
lcd.print("*PRATO BAIXO*");
lcd.setCursor(5, 1);
lcd.print("*PULL*");
delay(random(200, 3000));
digitalWrite(led3, HIGH);
delay(400);
digitalWrite(lamp2, LOW);
digitalWrite(led3, LOW);
delay(3000);
lcd.clear();
lcd.setCursor(2, 0);
lcd.print("*AGUARDANDO*");
lcd.setCursor(3, 1);
lcd.print("*COMANDO*");

}
}

The state change detection example shows how to count button switch presses. My addition to that tutorial covers state change detection using active low (wired to ground) switches.
