Is it possible?
I want to get some inputs via the arduino from a melodeon with the reeds taken out. The digital inputs will be from the buttons on the melodeon and a pressure/vacuum switch (to sense bellows direction). The analogue input will measure the pressure in the bellows, maybe through a strain gauge.
The signals will go to the phone so that software on the phone can produce tones equal to the notes depending on button pressed and bellows direction in/out (+ve pressure/-ve pressure)
The user will listen via headphones from the phone so as not to disturb neighbors.
