Automatic Guitar Tuner

The Automatic Guitar Tuner is a device that is designed to automatically tune a bass guitar to one of five different tuning preferences. The team picked this as their senior design project because it was interesting to all of them and would challenge them to use the skills they had learned throughout the electrical engineering program at UCF. It includes knowledge of digital signal processing, analog signal amplification, motor control, mounting design, C programming, Java, and electrical network configuration.

The Automatic Guitar Tuner uses a mobile Android application to select the desired tuning preference. Once the user has made the selection for the tuning preference, the systems microcontroller recieves a signal from the Bluetooth module and accesses the appropriate signal comparison algorithm. From there the user simply plucks each string individually, starting with the thickest (ending with the thinnest) and the motors mounted to the tuning pegs will automatically adjust the strings tension until it is at the correct frequency.
