Using the 433MHz RF Transmitter and Receiver with Arduino

433 MHz RF Transmitter and Receiver Module

While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where communication is one way (Receiving device cannot transmit and the transmitting device cannot receive).

Several options exist for implementing any of the two communication modes mentioned above and the selection of a particular option, usually depends on the specification of the project, especially the distance between the devices and cost. For short range, low-budget communication between two microcontrollers, one of the most preferred medium used is Radio Frequency (RF) communication using the 433MHz RF transmitter and receiver modules. For today’s tutorial, we will look at how to use these modules to establish communication between two Arduino boards.
