The document describes a project to automatically tune a guitar using a microphone, data acquisition hardware, and LabVIEW software. The system measures the frequency of plucked guitar strings using a microphone and stepper motor. It turns the tuning pegs until the string frequency matches the desired note. The results showed the system could consistently measure frequencies, though some strings were off by over 20 Hz from the expected frequency. Improvements could involve amplifying the guitar sound, a stronger motor, a more accurate microphone, and a friendlier user interface.
