When I click on the button, it just won't stop. It even start before I press the button.
please help "error code"
Thankyou

Since you did not specify INPUT_PULLUP for the buttons do you have a pulldown resistor included in your circuit?

Is your button wired to + or GND? The simplest way to wire a button is to wire it to GND, specify INPUT_PULLUP for the pinMode, and check for a HIGH to LOW transition to detect the button being pressed.

3

My button is hooked up to GND and i just can't seem to stop the music, both. Whenever I turn to Starwars music, it play once and turn back to Halloween music, and where do I put the INPUT_PULLUP?

Configure buttons for INPUT_PULLUP:

void setup(){
  //make the button's pin input
  pinMode(halloween, INPUT_PULLUP);
  pinMode(starwars, INPUT_PULLUP);
}

Since your button is wired to GND the input will be LOW when the button is pressed:

  if (digitalRead(halloween) == 1) {

should be

  if (digitalRead(halloween) == LOW) {

and

  if (digitalRead(starwars) == 1) {

should be

  if (digitalRead(starwars) == LOW) {

I did change what you asked, but It still doesn't stop, can anyone check this code?

Post your wiring diagram. I can't see why it won't work. The easiest way to debug would be to take out the music and print to serial to serial monitor what you are reading from each pin. When you are able to read pins properly then put the music back in. Like this:

const int halloween = 2;
const int starwars = 7;

void setup(){
  pinMode(halloween, INPUT_PULLUP);
  pinMode(starwars, INPUT_PULLUP);
  Serial.begin(115200);
}

void loop() {

  if (digitalRead(halloween) == LOW)
  {
      Serial.println("halloween is LOW");
  }
  else
  {
      Serial.println("halloween is HIGH");
  }
  if (digitalRead(starwars) == LOW)
  {
      Serial.println("starwars is LOW");
  }
  else
  {
      Serial.println("starwars is HIGH");
  }
  delay(250);
}

I added the 250ms delay so you would have so many prints.

Yes, I got it to work, Thank you very much

You’re welcome!
