## What it is
An Arduino library for sending and receiving infrared remote control signals across many IR protocols. It lets Arduino sketches decode signals from IR remotes and transmit IR commands to devices.

## Use cases
- decode signals from a TV remote with an Arduino
- control an LED strip with an IR remote
- send IR commands to a TV or air conditioner from Arduino
- build a universal IR remote
- capture and replay IR codes
- reverse-engineer an unknown IR protocol

## When to choose
- you need IR send/receive on Arduino or compatible microcontrollers
- you want broad multi-protocol IR support in one library
- you need a well-maintained, widely used Arduino IR library

## When to avoid
- you need RF, Bluetooth, or WiFi remote control instead of infrared
- you are not on an Arduino-compatible embedded platform
- you need IR on a full OS like Linux desktops

## Facets
- artifact type: library
- maturity: stable
- function: embedded, sdk
- domain: embedded-systems, hardware
- platform: embedded, cpp, iot
- tags: arduino, infrared, ir-remote, ir-protocols, electronics, automation
