Automatic Guitar Tuner

Senior Design Project

Automatic Guitar Tuner (Intunegrated)

• Collaborated within a group of 4 for the entire senior year.
• Presented during weekly meetings and progress reports.
• Researched how guitars worked and how different existing tuners worked.
• Tasked with designing the entirety of the project within the first semester.  Then creating a prototype in the second semester.
• Designed electrical schematic of the overall system using NI multisim.
• Found parts and kept track of pricing of all components.
• Set schedule and deadlines for different project milestones.
• Utilized a fast fourier transform to find the recorded frequency 
• Tested different DSP algorithms using MatLab to find the most accurate.
• Designed gear mechanism to hold string similar to a tuning peg.
• Communicated with motors via I2C communication.
• Created I2C driver specifically for our project and micro controller.
• Programmed real time code in C using embedded systems.
• Designed a control system to spin a DC motor for a specific amount of time.
• Successfully tuned a guitar mockup to multiple different notes.
• Presented design at the end of the year to faculty, investors and anybody that was curious.
