Counting problem

Projects Programming

Hey guys, currently i am trying to make a really simple program that will increase a count by +1, display it in the serial monitor, and then stop the sequence but I ran into a problem. It just keeps looping my first "if" statement and ignoring the "else" part. I think I might be overlooking something very simple..

Here's the code

#include <SPI.h>

void setup()
{
  Serial.begin(9600);
  SPI.begin();
  
  
}

void loop()
{
  int studentsSIGNEDIN=0;
  int signedIN=1;
  int notsignedIN=0;
  
 

  {
   if (notsignedIN != signedIN)
   {
    studentsSIGNEDIN++;
    Serial.println("Student has been signed in");
    Serial.print("Total number of students signed in right now is:");
    Serial.println(studentsSIGNEDIN);
    }
      else
        {
          Serial.println("Student already signed in");
        }
        
  }
  notsignedIN == signedIN;
  delay(2000);
   
}

Here's a picture of the serial monitor:

notsignedIN == signedIN;
You mean
notsignedIN = signedIN;

Thanks for the reply Larry!

I tried editing my code to reflect your suggestion but I still seem to be getting the same results..Could it be anything else that is causing the problem?

int studentsSIGNEDIN=0;
int signedIN=1;
int notsignedIN=0;

Move these out of the loop() function
i.e. make them global

Ahh.. there was the problem! Thank you so much for your quick responses
