Example Circuit

Using the 1MΩ load resistor dampening method described above, here's a simple example circuit demonstrating how to hook up the vibration sensor:

Piezo hookup example

The Piezo is grounded on one end, and a generated voltage is routed to the Arduino's A0 ADC pin. Reading the voltage at that pin should give us an idea of how much the piezo is moving.
