## What it is
A lightweight Arduino library that provides low-power sleep and power management functions for AVR and SAMD microcontrollers. It supports idle, standby, and power-down sleep modes across a range of ATMega and ATSAMD chips.

## Use cases
- put an arduino to sleep to save battery
- reduce power consumption on atmega328p
- wake microcontroller with external interrupt
- battery-powered sensor node sleep modes
- low power standby on samd21

## When to choose
- you use a supported AVR or SAMD21 Arduino board and need simple sleep APIs
- battery life is critical for your embedded project

## When to avoid
- you use an unsupported microcontroller or non-Arduino platform
- you need fine-grained power management beyond basic sleep modes

## Facets
- artifact type: library
- maturity: maintenance
- function: embedded
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, iot, cpp
- tags: arduino, low-power, sleep-modes, atmega, samd21, power-management
