Mechatronics Project
Automated Guitar Tuner using PID Algorithm 
Abstract:
Tuning guitars is often challenging, with existing solutions like manual tuners and apps being complex, inefficient, or expensive. Our project introduces a PID-controlled automatic guitar tuner, utilizing a microphone for pitch detection across different guitar types and environments. Our system employs a PID algorithm for precise frequency analysis and a stepper motor with a gearbox for tuning key adjustments, offering a superior, cost-effective alternative.  
This approach ensures reliability and simplicity in tuning, addressing the limitations of existing tuners by providing a user-friendly, efficient solution. Our method facilitates quick and accurate tuning and supports educational applications, aiding both beginners and professionals. The combination of acoustic signal processing and mechanical actuation demonstrates the potential of integrating technology with traditional musical practices, enhancing the tuning process's accuracy and efficiency.
