I have built a circuit to amplifiy the signal from 2 piezo (using an Opamp). It work as expected. Using a Parallax Stamp I can read when each piezo is activate. No problem there. I added an ADC0831 to be able to read how hard the piezos were hit. For this application I don't need to know how hard each piezo was hit, an average will do. The problem is the signal cross over the other and I am not able to determine which one is active. I am sure is the way I connect the signals (A and B) to the ADC and to each pin (PIN 1 and PIN2), but cannot figure out how to make it work. How do I isolate each PIN signal (PIN 1 and PIN2) but be able to combined each signal for the ADC?
