Summary
The article describes a Guitar Tuning Project using an Arduino Uno and a TL082 op-amp to detect audio frequencies from a guitar. The Arduino runs frequency detection software, lighting LEDs corresponding to specific guitar string frequencies (E, A, D, G, B, E). The system is powered by two 9V batteries, and the project includes connection diagrams and source code for setup.Parts used in the Guitar Tuning Project with Arduino Uno:
- Arduino Uno board
- TL082 operational amplifier
- LEDs
- 9V batteries (2 pieces)
- Cables and connectors
- Guitar (audio input source)
- Software: Arduino Frequency Detection code
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… Electronics Projects, Guitar Tuning Project with Arduino Uno “arduino projects, avr project, microcontroller projects, “
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)
