Like a pager
OK, I think I need to clarify things again.
I want to reproduce exactly what a common (CST type) pager does, now I may be wrong but I thought it has a small piezo sounder in there and it was driven from 1.5v (obviously boosted, but to what level I do not know)
I found lots of piezo sounders and all I need now is the driver, I'm no electronics wizard (very part time newbie) so making my own was out of the question, so I looked for drivers IC's, found some but cannot get supply of these.
So, I came here hoping that this had been done before and to find a fully explained schematic of a simple (low part count) driver circuit or better still a IC that does it all as the sounder is only one small part of my project.
Hope this clears things up and helps you help me
Thx again for help so far
