Hi to all,
Its a rainy day here and I thought I would finally get round to making a few circuits I have been meaning to try for ages.
I came upon a circuit for a Piezo buzzer on the web and was just going to build it when I noticed that it has, or seems to have 3 connections on the piezo element!
Are there 3 pole piezo elements or is there something I'm missing about the drawing?
Thanks Al
