Source code

volatile int pulses = 0;
const byte interruptPin = 2;
boolean displayMe = true;

void setup() {
    Serial.begin(9600);
    pinMode(interruptPin,INPUT_PULLUP);
    attachInterrupt(0,countPulses,CHANGE);
}
void countPulses(){
    int val = digitalRead(2);
    if(val == LOW){
       pulses++;
       displayMe = true;
    }
}
void loop() {
   if(displayMe == true){
      Serial.println(pulses);
      displayMe = false;
    }
}
