RFM69HCW Hookup Guide

Resources and Going Further

For this tutorial, we connected both of the nodes to the same computer to make it easy to send messages from one node to another. But, remember that when you do your own projects, your nodes might be attached to weather stations, garage doors, Halloween decorations, drones, robots, your cat... the sky's the limit!

The example code has comments that explain how messages are sent and received. Feel free to use it as a basis for the code in your projects.

For advanced usage, you can also check out the other examples and source code in the library. The RFM69.h and RFM69.cpp files list all of the library functions and tell you a little bit about what they do.

• SparkFun Product Showcase: Transceivers!

This transceiver is great for projects like building a remote kill switch to terminate power to your project when your robot goes... sentient.
