motion/vibration sensor with piezo

Another possibility?

I've just “found” one of these in my junkbox:

And remembered this thread:

Use the sensor like the switch in manual 3, p25.

I've just modified Ylp's original program slightly

Code:

ContactOpen:
if pin0 = 1 then OPToggle
goto ContactOpen

ContactClosed:
if pin0 = 0 then OPToggle
goto ContactClosed

OPToggle:

high 1
pause 1000
low 1 
pause 1000

if pin0 = 1 then ContactClosed
goto ContactOpen

It works very well on breadboard.
