Can you copy this code and paste it into the IDE and get it to compile? Be sure to select nano in the IDE tools->board = "Arduino Nano". This is for an ultrasonic device but for testing you do not need  the device:


  
#define trigPin 9
#define echoPin 10
long duration;
int distance;
long firstoff;
int distancefirst;

void setup()
{
Serial.begin(9600);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
delay(1000);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
firstoff = pulseIn(echoPin, HIGH);
distancefirst = firstoff*0.034/2; // cm
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance= duration*0.034/2; // cm
//distance = duration * 0.0133 / 2; // in
Serial.println(distance);
delay(1000);
Serial.println(distancefirst);



if (distance <= distancefirst - 5)
{
tone(3, 500, 500);
delay(500);
tone(3, 800, 500);
delay(500);
delay(50);
}
}

It is the first project from: https://create.arduino.cc/projecthub/projects/tags/nano
