Frequencies

I am designing a tone generator for a siren that a friend is building. He has speakers and he needs a tone generator.

I want it to sound like the start-up noise heard in the beginning of this video
I tried some stuff with for...next but it made the whoop too fast and it seemed to skip.

I want one that goes slow and is smooth. Can anyone help me accomplish this? Thanks!

OK, I'll Reply.· I read this when it was first posted --·and I kept right on walking.

The Stamp's FREQOUT is not suitable as a complex sound generator.

Now you'll have lots of Replies.


Post Edit -- A Stamp could be used to control this: http://www.speechchips.com/shop/item.aspx?itemid=14

There's more than one way to skin a cat with the Stamp. Try experimenting with this code:

' {$STAMP BS2}
' {$PBASIC 2.5}

FOR W0 = 1000 TO 100
    SEROUT 0, W0 >> 1, [noparse][[/noparse]0]
NEXT
