Subject: [AVR-Chat] alarm switch



Hi all,

I am looking an alarm type switch and am thinking of using a Tiny11
to generate a pulse of something like 10khz and then send that thru
the 6 to 10 switches (in series) and then use the same Tiny11 to
detect that pulse.  Any switch opens and the pulse is lost.

An alternate is to use a pair, one to generate and one to detect.

BTY, does anyone know if there will be another group buy ?

I doubt if Chetan will be organising another, as he's got all he needs. Why 
not organise one yourself?
