What is rfrf module?

RF Module comprises of a transmitter and a receiver that operate at a radio frequency range. Usually, the frequency at which these modules communicate will be 315 MHz or 434 MHz.

What is the receiver part of Arduino?

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 Receiver part is as follows.

What is the use of it library in Arduino?

It is a communication library that allows two Arduino’s to communicate with each other using RF Module i.e. transmitter – receiver pair. This library consists of several functions that are used for configuring the modules, transmission of data by the transmitter module and data reception by the receiver module.
