Communication Between Two Arduinos by 433.92 MHz RF Modules (Part 1 of 3)

<<<< Previous : Make a Double Sided PCB at Home

This is a 434MHz RF transmitter and receiver which is used for short range wireless control applications. Transmitter power supply ranges from 3 – 12V which makes it suitable for battery powered applications. I purchased RF transmitter and receiver from rhydolabz.

Images of a 434 MHz RF transmitter and receiver is shown below. Both transmitter and receiver have a data pin. Data given to the transmitter will be send to air. Receiver will receive the signal and can be easily taken through the data terminal of receiver.
