How do you reduce the arduino power consumption?
I found a few ways:
- Turn LED off
- replace delay(); with snore(); and the tinysnore library
- reduce clock speed from 16 mhz to 1 mhz
- use 3v instead of 5v
My questions are:
How do you reduce the clock speed from 16mhz to 1 mhz?
and how do you know if this has any implications for your arduino software?
Furthermore, how do you know you can use 3v instead of 5v?
