Guitar Sound Converter DIY Project
Hello Readers.
In this articles I am going to show an awesome project that I did in my free time. This project is basically a DIY guitar note recognition and play another instrument's note. the way this works is using computer's microphone I wrote a Node.js app that will listen and recognize the note that is played by the guitar, and next it will pass that note via bluetooth to my arduino board and it has been setup with a sd card reader in which there are sound files with .wav extension. This sound file is instrument specific so for example if we need to play piano then piano c major scale note sounds will be saved in the sd card eg : C.wav.
So when ever the arudino recieves a note from the computer via bluetooth, the arduino will open and play that note specific wav file and as a result when guitarist play each note, the arudino will playback the wav file for each note assigned.
This way I was able to play the guitar while arduino plays the piano or what ever instrument sound that I have placed inside the SD card.
