Hi out there in Usenet electronics land.
Was hoping to get a little help on something that should be pretty simple.
I want to vibrate a metal plate at different frequencies using a piezo buzzer or transducer of some type for some Cymatic experiments.
I can use the output from a computer or stereo to generate lots of tones but how do I drive a piezo element with a speaker output ?
This question is probably embarassingly easy to answer but I have never used a piezo element for anything other than creating a spark to light my cigarettes. :)
Thank you in advance.
