Hello all,

I would greatly appreciate it if you could help me!
I am needing to use some buzzers in a project I am working on and I've been recommended to use piezo discs. I've purchased these discs (small, gold things) but I dont know about the circuit that has to accompany to make buzzers out of them. Does anyone know how I can use these piezo discs as buzzers?

Thanks in advance if there's anybody out there who can help,
-G

 

Take a look at the piezo-electric circuit examples on Dave Johnson's Discover Circuits Website.

You can also get a few ideas on how to drive these sounding devices here.
