Esto...

```arduino
  duration = pulseIn(echopin, HIGH); // <== look at your code here

```

Tu código tiene algunos errores de código y líneas que faltan. Revisa tu trabajo.

```arduino
const int trigpin = 9;
const int echopin = 10;
const int ENApin = 6;
const int IN1pin = 7; // <== added
const int IN2pin = 8; // <== added
float duration;
float distanceCM;

void setup() {
  Serial.begin(9600);
  pinMode(trigpin, OUTPUT);
  pinMode(echopin, INPUT);
  pinMode(ENApin, OUTPUT);
  pinMode(IN1pin, OUTPUT); // <== added
  pinMode(IN2pin, OUTPUT); // <== added
}

void loop() {
  digitalWrite(trigpin, LOW);
  delayMicroseconds(2);
  digitalWrite(trigpin, HIGH);
  delayMicroseconds(10);
  duration = pulseIn(echopin, HIGH); // <== look at your code here

  distanceCM = duration * 0.034 / 2; // <== look at your code. speed of sound, return trip

  Serial.print("Distance: ");
  Serial.print(distanceCM);
  Serial.println("cm");

  if (distanceCM <= 100) {
    int motorSpeed = map(distanceCM, 0, 100, 0, 255); // <== look at your "map" code
    digitalWrite(IN1pin, HIGH); // on
    digitalWrite(IN2pin, LOW); // off
    analogWrite(ENApin, motorSpeed); // speed control with distanceCM
  } else {
    analogWrite(ENApin, 0); // speed zero
    digitalWrite(IN1pin, LOW); // off
    digitalWrite(IN2pin, LOW); // off
  }
}

Good morning. As requested, I am sending the compilation error I encountered; I am using a vibration motor and a button with an Arduino Nano. I have already fixed the spacing issue. As you have likely noticed, this is our first project—thank you for the help provided.

const int trigpin = 9;

const int echopin = 10;

const int ENApin = 6

float duration;

float distanceCM;

void setup() {

serial.begin(9600);

pinMOde(trigPin, OUTPUT);

pinMOde(echoPin, INPUT);

pinMOde(ENApin, OUPUT);

}

void loop() {

// put your main code here, to run

digitalWrite(trigpin, LOW);

delayMicroseconds(2);

digitalWrite(trigpin, HIGH);

delayMicroseconds(10);

duration = pulseIn(echoPin. HIGH);

distanceCM = DURATION 0.034)/ 2;

Serial.print("Distance: ");

Serial.print(" cm ");

if (distanceIN \<=100) {

int motorSpeed = map(distanceCM, 100, 200, 300);

digitalWrite(IN1pin, HIGH);

digitalWrite(IN2pin, LOW);

analogWrite(ENApin, motorSpeed);

}

else {

digitalWrite(IN1pin, LOW);

analogWrite(ENApin, 0);

}

}
