This might be in the wrong place and also might be the wrong approach.. I'm looking for a way of making my arduino to use less power when the battery runs dead (I'm using a voltage divider to apply a voltage to pin 5 from a lipo).
Does anyone know where I can download the library or if there's a better approach? I might get a Pololu Power Switch to cut the power off in this situation http://www.pololu.com/catalog/product/750
For now I'd like to just reduce the power to slow the batteries discharge.
Feel free to suggest a better place to ask this..
