How do you use a piezoelectric ceramic to light an LED?
I have a small, round piezoelectric ceramic sensor made from PZT (Lead Zirconate Titanate) material that I would like to try out to see how much mechanical force I need to apply to light a 5mm LED. The piezo ceramic has already been soldered with two wires (negative and positive). Nevertheless, I am completely new to creating circuits that involve a piezo ceramic. As a result, I have no idea whatsoever on how to properly connect the piezoelectric ceramic to the LED as to light it up. I have connected the two together before and applied force on the ceramic to see if it created some sort of charge, yet nothing occurred.
