motion/vibration sensor with piezo

[alexthefox]

Another possibility?

I've just “found” one of these in my junkbox:
http://www.rapidonline.com/Electron...-mercury-vibration-sensors/72379/kw/vibration


And remembered this thread:

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

I've just modified Ylp's original program slightly

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.

i bought the sensor from rapidonline about 5 mounth ago, but is is to much sense.
