BS2 siren code

Hello, I need some BS2 code for either this warning sound or this Klaxon alarm sound to be played 5 times on a piezo buzzer (connected to pin 0) and then stop. I don't need the graphics, I just need the sound.

    You are going to have to do some experimenting on your own. The BS2 is pretty limited in what sorts of sounds it can make and you'll have to decide what satisfies you. The main statement for sound making is the FREQOUT which can make one or two relatively pure tones (read the manual for details. The "warning sound" sounds like some kind of modem, changing between two tones at high speed to make that sort of warbling sound. The BS2 really isn't fast enough to do that, but you could experiment with one short FREQOUT after another in a loop with different frequencies.

    I finally got the klaxon horn sound!! I tried to put the recorded sound file onto the fourm as an attatchment, but for some reason, the file wouldn't show up!

    but it didn't work:frown::frown::frown::frown::frown::frown:
    That's not very helpful. Does it do anything? Do you get any errors?

    What I meant to say (I was pressed for time yesterday) was something like : "I tried to put the recorded sound file onto the fourm as an attatchment, but for some reason, the file wouldn't show up!!".

    Good job! I bet lots of people have made interesting sounds with the BS2. It sure would be nice if there was an ONLINE LIBRARY where people could post them to share. Kinda sorta like the object exchange. Any chance, Parallax?
