Greetings all...

I need to interface one of those cheap piezo disc transducer thingies to a pic via an adc pin - the sort of thing you can get in Maplins for 10p or whatever.

Last time I remember playing with one on the 'scope, it produced wildly varying output depending on how hard you hit it - as is its nature (!).

Is it possible to tame and scale this output to receive a value twixt 0-255 or should I be looking at a different kind of sensor?

I need something that responds to being hit !

Any thoughts?
