OK, I just want to say that im not an expert but not completely a noob either.
So i have my ThingShield plugged into the Arduino, it was recognized by the app and I can see it in the SDK but when i tried the examples I cannot get anything working. When i try the NetworkStatus LED Example ive only been able to get a green light which is UNKNOWN so it tells me absolutely nothing!.
Any suggestions? 
Did you load the appropriate sketch into the arduino?
If your just learning the arduino side, start here:

Hope this helps,

Do i need to load anything aside from the network status led sketch?
I did a little arduino tutorial and it seems easy enough, i got basic things working. But i cannot get the network status to change from green
I find this very odd. I uploaded the stLEDwithNetworkStatus sketch but added the line " Serial.println(tempstate);" and the result of that is it prints the number 5 which is odd because it isnt any of the cases which are state_leaving, state_joined_noparent, state_joining, state_no_network.
there must be something very simple wrong, i know that when its fixed ill be like “was that it”.
Do not buy arduino from EBAY! specially from china! some pins werent working and after pulling my hair, trial and error i managed to get it working by testing with some cables from pin x and y to pin 2 and 3 on arduino.
Glad you found it. You got a working 'duino now?
Uh Oh. Also know that there is a switch on the ThingShield labeled D0D1/D2D3 when working with the Arduino at the moment make sure it is always on D2D3.
