Hi,
I'm working on a homebuilt circuit, that will provide an anti-theft alarm for a bicycle.
I've been going down the routes of looking at various 555 timer circuits, making various beep beep noises, but prefer the sounds of some of the free mp3 sound files that are out on the net.
I've downloaded some of these files, and am wondering how I could put them on a memory chip of some type, and then be able to 'output' them at appropriate times, into a loud speaker..
Clearly, I'd need a chip to interpret the files held on the ROM chip (?), before it's output to the speaker? What would that chip be? Are there any off the shelf chips to do this sort of thing?
Sorry, I can't be more specific, as I don't know too much about electronics.
Thanks Jeremy Watts
