Arduino alarm on mechanical clock Answered

I am new to arduino and I am trying to hook a mechanical wooden gear clock to trigger an alarm or chime when the clock hands hit 12.
Does anyone know how I can go about this or any tutorial/instructable that does this or something similar?


Use a micro switch on the hands or even the gears inside.

so it triggers as the hand passes over it?
where is the best place to get a micro switch

You can get them all over the place. It's a matter of finding one that has it's lever the way that would best suit your needs.
