Print Variable to LCD and Add to it according to Sensor

Other Hardware Displays

** Found the solution, first the original topic then the solution is under it **

Hello everyone,

What I want to do is this, each time my IR sensor picks up movement and gives out 0 instead of 1,
I want a variable on the LCD screen to be added 1 to it.

For example:

"Pessoas: 0" Someone walks in front of it >>>> "Pessoas: 1"

Right now I am able to display the variable to the lcd, but I really don't know with my noobish code
skills how to do what I need.

Here is what I tried so far and obviously does not work the way I want it to:

#include <LiquidCrystal.h>
LiquidCrystal lcd(7,8,9,10,11,12);

void setup() {
  Serial.begin(9600);
  pinMode(2,INPUT);
  lcd.begin(16, 2);
  lcd.clear();
  lcd.print("Passantes:");
}

void loop() {
  int irread = digitalRead(2);
  Serial.println(irread);
  delay(540);
  lcd.setCursor(0, 1);
  lcd.print("Pessoas ");
  int Pessoas = 0;
  if (irread = 0);
  Pessoas = Pessoas + 1; 
  lcd.print(Pessoas);
}

EDIT.: Ok I was able to make it work by doing:

int Pessoas = 0;

void loop() {
  
  int irread = digitalRead(2);
  Serial.println(irread);
  delay(500);
  lcd.setCursor(0, 1);
  lcd.print("Pessoas ");
  if (irread == 0){
    Pessoas = Pessoas +1;
    lcd.print(Pessoas);
  }


}

My main mistake was putting the int inside the loop I guess. Now it works as it should.

Thanks everyone you can now close the topic. Hope this helps somebody.
