Hi,

Would like to find out how to connect multiple piezo elements (series or parallel) to give a signal to one analog input on arduino mega. Is there a limit to how many we can connect and if we need any conditioning circuitry?

What is the purpose of connecting several together?

Seems like you are trying to use them as microphones. Piezos are capacitors that generate their own voltage. Connecting them in series accomplishes nothing, so parallel it is. No additional circuitry is needed.

You may need to consider some amplification for you project.
