I haven't had 2 arduinos communicating with them (because that wasn't my aim) so I can't say if that's easy.
Getting them to communicate with the RPi wasn't too easy. IIRC the arduino side of things was fairly easy but the RPi wasn't straight forward, I had to email the person who wrote some examples for advice, I was clueless with what I needed to do.
The arduino side of my setup is pretty "dumb", all it does is transmit a payload of the temperature and another number every 10 seconds or so. It was getting the RPi to receive them that was harder.
You're probably best getting a couple, using some example sketches and getting something working, then adapt it to what you want to actually do. |
