RF Encoder and Decoder Controlled 4 Channel Relay

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). The receiver circuit is built around Arduino UNO board, decoder HT12D Module, 433MHz RF receiver module (RX), 4 Channel Relay Board.
