led chase effect?

hi im a beginner ...trying to do this tutorial Arduino Project 5: LED Chase Effect - YouTube

but i get this error : This report would have more information with

2

This report would have more information

It certainly could.

Try this:

void setup () {
  
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(7, OUTPUT);
  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(12, OUTPUT);
  pinMode(13, OUTPUT);
  
}

void loop() {
  
  digitalWrite(4, HIGH);
  delay(10);
  digitalWrite(4, LOW);
  delay(10);
  digitalWrite(5, HIGH);
  delay(10);
  digitalWrite(5, LOW);
  delay(10)
  digitalWrite(6, HIGH);
  delay(10);
  digitalWrite(6, LOW);
  delay(10)
  digitalWrite(7, HIGH);
  delay(10);
  digitalWrite(7, LOW);
  delay(10)
  digitalWrite(8, HIGH);
  delay(10);
  digitalWrite(8, LOW);
  delay(10)
  digitalWrite(9, HIGH);
  delay(10);
  digitalWrite(9, LOW);
  delay(10)
  digitalWrite(10, HIGH);
  delay(10);
  digitalWrite(10, LOW);
  delay(10)
  digitalWrite(11, HIGH);
  delay(10);
  digitalWrite(11, LOW);
  delay(10)
  digitalWrite(12, HIGH);
  delay(10);
  digitalWrite(12, LOW);
  delay(10)
  digitalWrite(13, HIGH);
  delay(10);
  digitalWrite(13, LOW);
  delay(10)
  digitalWrite(12, HIGH);
  delay(10);
  digitalWrite(12, LOW);
  delay(10);
  digitalWrite(11, HIGH);
  delay(10);
  digitalWrite(11, LOW);
  delay(10)
  digitalWrite(10, HIGH);
  delay(10);
  digitalWrite(10, LOW);
  delay(10)
  digitalWrite(9, HIGH);
  delay(10);
  digitalWrite(9, LOW);
  delay(10)
  digitalWrite(8, HIGH);
  delay(10);
  digitalWrite(8, LOW);
  delay(10)
  digitalWrite(7, HIGH);
  delay(10);
  digitalWrite(7, LOW);
  delay(10)
  digitalWrite(6, HIGH);
  delay(10);
  digitalWrite(6, LOW);
  delay(10)
  digitalWrite(5, HIGH);
  delay(10);
  digitalWrite(5, LOW);
  delay(10)
  digitalWrite(4, HIGH);
  delay(10);
  digitalWrite(4, LOW);
  delay(10)


}

There are WAY easier ways to do this but this is the simplest way to do it, if this is what you are trying to make. Also you may want to make delays longer than just 10.
