If you are working on an RF (433MHz/315MHz) or IR remote control project, you have likely encountered the HT12E (Encoder) and HT12D (Decoder) IC pair. Unfortunately, these essential components are not included in the default Proteus library.
In this post, I will show you how to download, install, and use custom Proteus libraries for HT12E and HT12D so you can simulate your wireless encoder/decoder circuits accurately. Ht12e And Ht12d Proteus Library File Download
This proves the decoder logic without needing a perfect library.
If you just need to simulate an RF encoder/decoder pair, use these native Proteus models: After downloading the correct
| Function | Proteus Native Part | Notes |
| :--- | :--- | :--- |
| Encoder | PIC16F628A (write 20 lines of code) | Full control, 100% simulation accuracy. |
| Decoder | PIC16F628A (write decoder firmware) | Better than HT12D for debugging. |
| Serial Data | LTC1196 (8-bit ADC with serial out) | Not same protocol, but good for practice. |
| Remote Control | TDA7000 + PT2262 (if available) | Rarely used. |
Recommended: Use two Arduino Unos in Proteus: Usually: If you are working on an RF
This is 100% reliable and you can find Arduino libraries for HT12E protocol online.
If you can't find a pre-existing library, creating your own is an option:
