How do I connect it to an Arduino?
Connect one lead to an analog input such as A0 and the other to GND. A high-value resistor, commonly around 1 MΩ, placed across the two leads helps bleed off charge and gives a cleaner signal.
Can it be used as a microphone?
It responds to mechanical vibration and knocks rather than speech. Its output is weak and uncalibrated, so it is not a substitute for a dedicated microphone module.
