I am continuing with trying to learn various programming skills, and now I want to get into wireless communication.
What I basically want to do is flip a switch on one Arduino, and have it send a message to another arduino to turn on an LED. I've looked online and found some things using XBEE, but I don't know if you guys would recommend anything else. Also, the instructions I've seen are kind of vague, I'd like to find something in depth.
I know this is a simple thing but I will continue to look for tutorials until someone answers. Thanks for your help!
