Vibration Sensor Matrix.

Hello,

I have total Newboid status so sorry if any of the following doesn't
make sense.

I am trying to wire a wooden wall with vibration sensors to detect
whereabouts a thrown ball hits it.

I have some piezos which give out a variable voltage when vibrated.

I have a BX-24 microcontroller which takes voltage up to 5V, current up
to 100 milliamps.

I have 2 questions.

1. How do I build a circuit to convert the piezo output into a safe
readable format for the microcontroller?

2. If I build a matrix of say 12 piezos and analyse the results in
software to estimate the position of impact (on the wall) how accurate
results could I expect?

Thanks for any guidance,

Gav
