R/C Arduino car question

Using Arduino Programming Questions
1

Hey guys, I recently started learning Arduino and as I first project I decided to make an R/C car (so original I know haha). The thing is, everything was going well until I installed a buzzer. I wanted to make it play a song as a claxon but when I do that, the car won't make any other actions until the music stops.

I guess it is because Arduino can't handle 2 functions at once so I wanted to know if it possible to make the car read my inputs (forward, turn, etc) while the buzzer is sounding.

I can paste the code if needed.

Thanks a lot!

I think it would be better. My crystal ball is in the dish washer.
Post your sketch, well formated, with comments and in so called code tags "</>" to see how we can help.
Have a nice day and enjoy coding in C++.

Is the buzzer working in a simple test program?

Post that code and your attempt to integrate it with your successful r/c code.

  // Notice how the iteration variable thisNote is created in the parenthesis
  // The for loop stops when it is equal to the size of the melody array
  for (int thisNote = 0; thisNote < songLength; thisNote++){
    // determine the duration of the notes that the computer understands
    // divide 1000 by the value, so the first note lasts for 1000/8 milliseconds
    int duration = 1000/ durations[thisNote];
    tone(11, melody[thisNote], duration);
    // pause between notes
    int pause = duration * 1.3;
    delay(pause);
    // stop the tone
    noTone(11);
  }
}

The thing is, in the app, once I press "W" it won't accept any other commands until I stop the W.

Some notations are in spanish because im spanish, if you don't understand something, just ask!
