Performance reference
Explanation about the purpose of the output signal of LED:
When any button of the remote control is pressed, the receiving end decodes, and after the correct decoding, the LED will output
A high level signal 1, when the remote control button is released, the LED output becomes 0. That is: only when the reception is valid and decoded correctly, it will be output.
