For classic 38KHz infrared remote signal reading, we've got a lovely STEMMA IR Receiver. But if you want to read infrared signals from remotes with different carrier signals, especially when you don't know the frequency, this Adafruit TSMP96000 "Code Learning" Infrared IR Receiver Breakout has the ability to detect IR signals from 20 to 60KHz and provide the carrier signal for analysis. This is used for "code learning" situations where you want your device to work with any IR remote control. https://elecena.pl/product/26001841/adafruit-tsmp96000-code-learning-infrared-ir-receiver-breakout 2024-05-30 https://elecena.pl/product/26001841/adafruit-tsmp96000-code-learning-infrared-ir-receiver-breakout 2025-09-26
