RF Encoder and Decoder interface with Arduino

Updated: Jul 2, 2021

This tutorial to learn, One of the easiest and cheapest ways to implement wireless communication is using RF Module (Radio Frequency Module). The transmitter circuit is built encoder HT12E Module , 433MHz RF transmitter module (TX) and a few discrete components. The receiver circuit is built around Arduino UNO board, decoder HT12D Module, 433MHz RF receiver module (RX), 4 LED and a few discrete components.

Components required

  • 433 MHz RF Transmitter and Receiver Module

  • HT12D Decoder Module

  • HT12E EncoderModule

  • Push Buttons (4 Nos)

  • LEDs (4 Nos)

  • Arduino Uno
