  • Decode Rolling Code 433Mhz Signals with Arduino

    I’m posting this here because of my frustration in interpreting signals from a 433Mhz rolling code garage door opener based on the HCS301 chip with Arduino. To start with, I’d like to say that I don’t think it’s actually possible to decode the encrypted part of the transmission. But the 66 bit payload transmitted by…
