Signal Input/Output

Receive and send infrared signals.
Supports 50 different IR and 3 RF protocols.Can receive 40 protocols concurrently.Small footprint and robust decoding.Receive and send can be used in the same sketch.Supports ATtiny, AVR and MegaAVR boards as well as ESP8266, ESP32, STM32, SAMD, RP2040 and Apollo boards.New: Fixed send timing bug for ESP32.

This library is compatible with the avr, megaavr, samd, esp8266, esp32, stm32, STM32F1, apollo3, mbed, mbed_nano, rp2040 architectures so you should be able to use it on the following Arduino boards:

Compatibility Note

Note: while the library is supposed to compile correctly on these architectures, it might require specific hardware features that may be available only on some boards.


To use this library, open the Library Manager in the Arduino IDE and install it from there.
