Resources and Going Further

Now that you've sent signed message between two systems, you are ready to integrate some security into your projects! In these examples we have used hard-wired serial messages between two Arduinos. That communication channel could be anything: Bluetooth, RFM69s, Wifi and the internet, you name it! Good luck!
