how to get tones for my Boe-Bot?

fisheater

Hi everyone I'm new to the forum.
I had a question about how to get tones for my Boe-Bot. I'm using my piezospeaker, i understand that i have to use different frequencies, but I'm not sure where do i get the music notes. I have a project i have to do and think it would be cool to play " "back in black" by ac/dc on my Boe-Bot. haha

Look at the FREQOUT statement in the Parallax Basic Stamp Manual (or in the Stamp Editor's help window).

Thank you,but i know how to write the program, i was just wondering how i get the different frequencies for a desired song.

On the What's a Microcontroller? product page, there's a link to an RTTTL program. This can be used to play ringtones that you can download from the internet. (Search "RTTTL" with Google, and you'll find them.)

The program on that link is way over my head is there an easier way to decode this:

Back In Black:d=8,o=6,b=180:4e5, 2p, d, d, 4d, 2p, c#, c#, 4c, 2p, f, e, d, b5, b5, a5, g5, 4e5

You have to decode it yourself by hand (or find or write a program to do it). The notes need to be translated into frequencies (in Hz) and durations (in milliseconds) and the pauses need to be in milliseconds. The program mentioned by Phil should be able to do this for you and play the tune.

Fisheater,

This site give you the frequencies of musical notes.

If you have sheet music, you can convert most tunes into something that you can recognize with a Stamp, but don't expect perfect notes.
