Multiple 443mhz Receiver s fail

Projects General Guidance
11

Thanks everyone for your input so far.
The RX470c-v01 "Superheterodyne" receiver gave a lot less noise than the MX-RM-5V, but both worked.

I attached it to 5V and the signal via a 220 ohm resistor

                                            SLEEVE —> GND

Now the question for me is, how do I make sense of the signal

According to this guide

I am looking at a pulse position modulation (ppm) signal. I decoded one of the Buttons signal by hand.

So the signal is:
0000 1100 1111 0001 0001 1000 1110 10111

What do I do now? rtl_433 does not mention opening audio files in the documentation. Do I need to do this by hand for all buttons? Since I am now certain that the receiver works fine, I should be able to make it play nice with the Arduino, no? And what do I do now to send this signal? In case anyone is curious to listen to my remote, I included the on key for your enjoyment.
