How to put arduino in sleep mode?

Question

I need to put arduino in sleep mode. I did not find the library avr/sleep.h . From where to download it.

Answer 1

avr/sleep.h is part of the compiler. You don't need to download it.

There are other libraries that act as a wrapper to it to make life easier:
