Hello all. As a Digital project, I'm trying to construct a digital guitar tuner that will actually tune the guitar for you, all you have to do is put the device on the tuner and pluck a string. My problem is I'm not very mechanically inclined... Does anyone know a tiny hobby motor with a very low RPM (it only takes the slightest touch usually to tune a guitar). It'd be nice if it ran off of 5V (so I can get the digital components and motor off the same supply), reversibile (for tuning up and down), and some kind of guide for motor basics?? If this exists can you point me in the right direction?
