Hello, I need help with this, if anyone knows the code and how to do it on the breadboard I would be grateful

Why did you not just copy the code from the video? (see Post #4)

ino 
#define PIN_TRIG 3
#define PIN_ECHO 2
int led;

void setup() {
  pinMode(PIN_TRIG, OUTPUT);
  pinMode(PIN_ECHO, INPUT);
  for (int i = 4; i < 7; i++) {
    pinMode(i, OUTPUT);
  }
}

void loop() {
  digitalWrite(PIN_TRIG, HIGH);
  delayMicroseconds(10);
  digitalWrite(PIN_TRIG, LOW);

  led = pulseIn(PIN_ECHO, HIGH) / 6000 + 5;

  for (int i = 4; i < led; i++) {
    digitalWrite(i, HIGH);
  }
  for (int i = led; i < 8; i++) {
    digitalWrite(i, LOW);
  }
}
