I am also new to this. You definitely need to create the smart things ecosystem device handler that correspond to this arduino sketch.

That makes sense. I'm using the "On/Off Shield (example)" device type and I have this loaded onto my Arduino. However, only the Hello button seems to generate a message and even that doesn't seem to be coming out right. I've attached a picture to show what I'm getting. I feel like there should be something in the 'value' row at the bottom. I crossed out some pieces of information, maybe unnecessarily; hopefully it's not needed to diagnose the problem.
