I had to comment out line 22 because it was giving an error in the simulator.

Is this still correct/applicable?
This code is the ONLY code i've seen for all the other device types that uses the Map parse(String description) code.
I haven't seen this code anywhere else in any of the sample event types, and, in fact, the "On/Off Shield (Example)" isn't even listed any more.

I just got everything setup and the on/off button is not working. The hello button works fine. Using a new hub, a new Arduino Shield, the latest lib, and the on/off example from the web site, unmodified.

This code do not show text coming from Arduino. However, there is a built in device type with this name which show that on the time. Don't know how to get that done. Ex. "buttonhello" example has a line item "smartthing.send("fancy");" with which can show "fancy" in a time. Don't know how to get that.

To fix change line 33 from
valueTile("message", "device.greeting", inactiveLabel: false) {

to
valueTile("message", "device.message", inactiveLabel: false) {
