So the adventure starts with this Arduino setup

 

And then some code to run it



int hallsensor = 9;
const int ledPin = 6;
const int ledPinWarn = 7;
const int ledPinStop = 8;
const int resetIn = 2;
const int resetOut = 3;
int wrapcount = 0;
int count1=0;

void setup()
{ 
pinMode(hallsensor, INPUT);
pinMode(resetIn, INPUT);
pinMode(resetOut, OUTPUT);
pinMode(ledPin, OUTPUT);
pinMode(ledPinWarn, OUTPUT);
pinMode(ledPinStop, OUTPUT);
Serial.begin(9600);
 digitalWrite(resetOut, LOW);

}

void loop()
{ 
int hall = digitalRead(hallsensor);
int reset = digitalRead(resetIn);

if (hall == 0) {

 if (count1 < 1){
    for (int i=0; i < 1; i++){

  // digitalWrite(ledPin, HIGH);
 PORTD |= 0b01000000;
wrapcount++;
count1=1;
  }
 }
}
    else {
  //digitalWrite(ledPin,LOW);
 PORTD &=~_BV(ledPin);
 count1 = 0;


  }
 
  if (wrapcount > 390 ){
  digitalWrite(ledPinWarn, HIGH);
   if (wrapcount > 300 ){
  digitalWrite(ledPinWarn, LOW);
  digitalWrite(ledPinStop, HIGH);
  }
  }
   if (reset == 1){
 digitalWrite(ledPinWarn, LOW);
  digitalWrite(ledPinStop, LOW); 
  wrapcount = 0;
  }
  Serial.println(wrapcount);
 
}
