Creating New Electronics for a guitar tuner

Hello,

I am working on a product that will include a guitar tuner in it and I'm not sure how to make the electronics. Does Arduino have a custom design section where I can send in specifications of what I need and get help on making the product work? Thank you

John

There are tons of chromatic guitar tuners, from the type that clip on & pick up vibration to the kind that use a built in mic, from as little as $9.

You want to duplicate something like that?

There's also this one : Digital Chromatic Guitar Tuner (2008) which takes an electric guitar input too. That page has a really good write-up of the mathematical theory behind the tuning method used too.
