As the title says, the serial monitor is not working with my project.
I click on the option and it minimizes but I cannot select it.
I need it to check if my PIR is working

What exactly are you clicking on ?
Can you open the Serial Monitor from the IDE menu Tools/Serial Monitor, or using the hotkey combination ?
Incidentally, there is no output to the Serial monitor in your code so there will be nothing to see anyway
Yes, thanks, I've solved it.
int sensoreValue = digitalRead(pinSensorePIR);
Serial.print("Valore del Sensore PIR: ");
Serial.println(sensoreValue);
I now have a problem with the lcd.
When the PIR receives an input the lcd flickers off and on
Is there a way to avoid this?
You are clearing the LCD every time through loop().
Do you need to do this as it will cause the LCD to flicker. Could you only clear the LCD before a new value is written or maybe just overwrite the previous value on the LCD without clearing the LCD.
I've solved it removing all the delays

Problem now is that the led furiously keeps going on and off while I'm moving in front of it.
Is there a way to pause the PIR activity after every loop?
