Guitar Tuner
Designed by Tony Chai and John Yi
This project entails creating a full-functioning automatic guitar tuner. It is capable of tuning
guitar string pegs automatically to tune a guitar to a variety of tunings. This provides a remedy
for two types of guitarists: one is for the professional, who may not be able to tune his strings
by ear in a loud environment and wants his strings tuned instantly. The other is for the novice,
who may not have the trained relative pitch necessary to tune the guitar himself. We also
aimed to make this device affordable, so that the potential users would not be intimidated by
the price point for being able to tune his guitar conveniently.
The tuner is manually attached to the target guitar peg. The guitarist will use a button to select
which string he wants to tune, and then pluck the according string for the tuner to correct the
guitar tuning. If the guitar is in tune, a green LED will light up indicating that it is in tune. If it
is either sharp (too high) or flat (too low), the tuner will . . . .
