two arduino communicate via LAN or Internet. LED on / off example?
want to set up so I can use a button on one to send information. and an LED on the other (slave?) that will turn on when the button on the "master" is enabled.
I've looked back and forth on forums etc. without found any sample code for such communication.
does anyone have such a code? or know where I can get such a code for this?
assume there is hope to find that up in internet
Hoping for good and helpful answers
Best regards. Vegard
