the encoder ic HT12E | Microcontroller › AVR › how to interface remote controller with HT12E and to RF Tx › the encoder ic HT12E June 10, 2013 at 8:18 am #9930 ShrikantParticipant the encoder ic HT12E basically does parallel to serial conversion. The entire setup is a ASK method Similarly at the receiver the decoder ic HT12D does serial to parallel conversion after getting the data from the Rx Hope this was helpful
