## Component IR Learn

This is an RMT-based `IR Learn` component that can receive to analyze infrared signals with a `38KHz` carrier. The signal collected by the component is saved and forwarded in the form of `raw`, and the specific analysis of the infrared protocol is not supported now.

## How to Use Example

### Hardware Required

* A development board with supported SoC mentioned in the above `Supported Targets` table
* An USB cable for power supply and programming
* A 5mm infrared LED (e.g. IR333C) used to transmit encoded IR signals
* An infrared receiver module (e.g. IRM-3638T), which integrates a demodulator and AGC circuit
