The idea of this project was to change the way we play a traditional piano by changing the keys to different Arduino sensors.
The sensors were selected based on haptics and interactions such as blowing into the "key" to generate sound. Every key required different physical interactions with the user
The first and most basic key was a switch that emitted the "do" note. Afterwards we had more complex sensors for each key. "Re" note was played by blowing into an electret microphone. "Mi" and "fa" were played by moving a palette up and down in a box, each key had a specific position in the height of the box (this was made possible by using a parallax ping sensor). "Sol" was played by positioning a box upside down (using a tilt sensor). Lastly, "la" and "si" were played by moving a palette deep in water, the deepness of the palette defined the note.
Here's a video that shows all the notes in use:
We realized that when we played different notes at the same time the mechanism actually turned into a synthesizer that could create cool music, this was not our initial goal but it made the object much more interesting.
Here's are a few videos of the synthesizer in use:
This project was created as part of a class project at Los Andes university.
