We recently ordered some very cheap RF modules online to test out with our Arduino’s that we have here, despite being very cheap products they do seem to work incredibly well – So much so that we thought they deserve an article on how to get them up and running and working with two or more Arduino’s (with example sketches)
First of all, the components you’ll be needing are:
- 1x Arduino
- 1x XY-MK-5V 433Mhz RF Receiver
- 1x FS1000A/XY-FST RF 433Mhz Transmitter
- VirtualWire Arduino Library
You’ll need a basic understanding of the Arduino IDE and basic programming skills to implement the example code posted below.
