The ability to simulate wireless encoders and decoders is critical for RF projects. By downloading the from a trusted source and following the installation steps above, you can now design, test, and debug 4-channel wireless remote controls entirely inside Proteus—before soldering a single component.

I have packaged the files into a ready-to-use ZIP. Ht12e And Ht12d Proteus Library File Download
Click on Library > Component and select Ht12e or Ht12d from the list.

Close and reopen Proteus ISIS.
This 18-pin companion IC receives the serial bit stream from the encoder. It decodes the transmission and updates its 4 data output pins (D8–D11). The decoder only outputs the data if its 8 address pins (A0–A7) exactly match the address configuration set on the HT12E.

You need to paste the downloaded files into the correct folder so Proteus can "see" them.
Data outputs. Connects to LEDs, logic probes, or microcontrollers to display received states.
Connect address pins A0 through A7 to ground on both ICs. The address configurations must match exactly for data transmission to succeed.
