Arduino code for combining a compressor and a guitar tuner in one DIY pedal.
In combination with the use of a OLED display (128x64).
Attention: This project isn't finished at all and is still in raw development.
- Tuner -> The function to measure the frequency comes from the following website. It was the most accurate measuring I found. [http://www.breadboarding.de/frequenzmessung-arduino/]
