The receiver part consists of Arduino UNO and the 434 MHz Receiver module. An external LED can be used along with a current limiting resistor but on board LED would be sufficient. The design of the ...

Transmitter and Reciever shields based on RFM96W LoRa modules. Each shield is a protoshield consisting of the RFM96W with an associated LED, with a transmitting frequency of 433MHz. The transmitter ...

Arduino and 433MHz RF Module Circuit Diagram. Circuit diagram for this Arduino transmitter and receiver is shown below. Connecting the Tx module to the 433MHz RF link is very simple. Connect the ...

The receiver and motor driver circuit (Fig. 3) is built around Arduino UNO board (BOARD1), decoder IC HT12D (IC2), 433MHz RF receiver module (RX1), motor driver IC L293D (IC3), regulator IC 7805 (IC4) ...
