If we want to implement the project without the library, then we need to change the receiver part of the circuit. VirtualWire.h is a special library for Arduino created by Mike McCauley. It is a ...

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 ...

Here at RF Transmitter side, we have used Arduino Nano. Wiring the receiver module is also very simple, and once again you only need to make three connections. Connect the modules VCC and ground pins ...

Arduino RF Transmitter Circuit Diagram Our wireless doorbell project will require a transmitter and receiver circuit each with its own Arduino board. The Circuit diagram for Doorbell Transmitter is ...

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) ...
