Hey guys, i was wondering if i could get some advice...
I'm looking to get a high logic level on a PIC18f and a basic stamp 2 IC pin when a moderate amount of pressure is excerted on a piezo film transducer from rs:
(http://uk.rs-online.com/web/p/produ...2267573743D3732342D333136322677633D4E4F4E4526).
The problem is my project is complex enough for me and I don't really have the time to implement an ADC and measure voltage relative to pressure, so I was wondering if i could attach the live terminal of the piezo disk to one input of each IC, and put 2 opposing diodes running to earth in between the piezo and the IC's (whlie grounding the ground of the disk)
I sorry if this isn't too clear, but im having difficulty posting my image...i'm new to forums
if you would like any more details of my project, or if there's anything else I could help you with then give me a shout.
any suggestions would be brilliant
