This project might not be as easy as you think,
We can get the note easy enough but not the octave.
There are 7 major musical notes denoted by the alphabets; A, B, C, D, E, F, G
- Amplifying: here we use a o-amp
well we need to prevent clipping of the signal; doing so we need to offset the voltage of the signal.
Is it enough to simply fish the electrical signal at the jack socket, or do you place a piezo? Or both?
Then connect high and low pass in hardware before going into the ANALOG-IN, or let the ARDi do it?
