Guitar Tuning Project with Arduino Uno

Arduino Uno kit on the Board at the entrance of the TL082 opamp used Guitar Tuning circuit audio audio input and frequency to detect the “Arduino-Frequency-Detection” software used.

According to the LEDs light at certain frequencies sesisnin the guitar.

E – 82.4 Hz
A – 110Hz
D – 146.8 Hz
G – 196Hz
B – 246.9 Hz
E – 329.6 Hz

Guitar Tuning system works with 2 pieces of 9v battery connection diagram and source code box for the panel was given in diagrams (corel, photoshop)
