How to use low power mode

How to use low power mode
« on: April 17, 2014, 08:27:30 AM »
I have a project where I want to use the TinyDuino and accelerometer in a low power mode.  Ideally the TinyDuino would sleep for bit, maybe 15 seconds, wake up, check the accelerometer.  I plan to attach the TinyDuino to a the side of a spool that is slowly turning (it's the filament spool for my 3D printer).  If the spool stops rotating, TinyDuino will send out a wireless signal using an RF Link like this one: https://www.sparkfun.com/products/10534.

So I need to know how to setup the TinyDuino for low power mode; I also need to setup the accelerometer for low power.  How do I do this?

Nick Gammon's site really helped me to understand low power modes and to get the sleep function working with a chronodot RTC:
