An external LED can be used but on board LED would be sufficient.

The transmitter part consists of Arduino UNO and the 434 MHz Transmitter module. This module can be used for communication for distances up to 40 meters. In this project, we are using a 434 MHz RF Transmitter – Receiver pair. Usually, the frequency at which these modules communicate will be 315 MHz or 434 MHz. RF Module comprises of a transmitter and a receiver that operate at a radio frequency range.

RF Module is a cheap wireless communication module for low cost application. In this project, two Arduino boards will communicate using wireless communication. 434 MHz Receiver Module (or 315 MHz Module)Īrduino UNO is the low cost, open source, microcontroller board for electronics prototyping.434 MHz Transmitter Module (or 315 MHz Module).Arduino UNO (or any other Arduino board).The circuit for the Transmitter part of the project is shown below.Īnd the circuit for the Receiver part of the project is shown below. As it is a wireless communication project, the circuit consists of a Transmitter part and a Receiver part.
