Hello!  
I am still very new to this and I am working on a clock.  
I would like the clock to play a sound every hour. (Like clocks do 😉)  
I can load the sound into the file but then I am not sure how to tackle it.  
Does anyone know any examples that I could look at?  
Thank you!

for example here [https://www.processing.org/reference/libraries/sound/SoundFile\_play\_.html](https://www.processing.org/reference/libraries/sound/SoundFile_play_.html)

to check the hour use hour() maybe you can store the previousHour throughout and when they are different play sound (to avoid that it gets played multiple times)

see [https://www.processing.org/reference/hour\_.html](https://www.processing.org/reference/hour_.html)

Hey!,  
Yes I saw these two but I am not sure how I can combine these.

"import processing.sound.\*;  
int m = minute();  
SoundFile bang;

void setup() {  
size(640, 360);  
background(255);  
bang = new SoundFile(this, “bang.wav”);

}

void draw() {

if(m == 00){  
bang.play(); }  
noLoop();  
}  
"

This is how far I got. The problem is that I would like to run it every time the minute is 0, so every hour. for now it only runs once on the minute I run it. How do I run the program in a loop?

```auto

SoundFile bang;

int mPrev; 

void setup() {
  size(640, 360);
  background(255);
  bang = new SoundFile(this, "bang.wav");
  mPrev=minute();
}

void draw() {
  if (minute() != mPrev) {
    bang.play();
    mPrev=minute();
  }//if
}
