Enumerations
enum	SleepDuration {   SLEEP_15_MS, SLEEP_30_MS, SLEEP_60_MS, SLEEP_120_MS,   SLEEP_250_MS, SLEEP_500_MS, SLEEP_1_SEC, SLEEP_2_SEC,   SLEEP_4_SEC, SLEEP_8_SEC }
	Duration to put the CPU to sleep with sleepFor(). More...

Functions
void	sleepFor (SleepDuration duration, uint8_t mode)
	Puts the CPU to sleep for a specific duration.The analog to digital converter and the brown out detector will be disabled during sleep mode. More...
void	unusedPin (uint8_t pin)
	Marks an I/O pin as unused.This function sets pin to be an input with pullups enabled, which will reduce power consumption compared to pins that are left floating.

Detailed Description

The functions in this module assist with reducing power consumption on Arduino boards by disabling features that are not used or putting the device to sleep when it is inactive.

Function Documentation

void sleepFor	(	SleepDuration	duration,
		uint8_t	mode
	)

Puts the CPU to sleep for a specific duration.The analog to digital converter and the brown out detector will be disabled during sleep mode.

The mode parameter indicates the mode to use when the device is sleeping. The default is SLEEP_MODE_IDLE.
