Great shield and app! The shield is great. The code examples make using the shield easy. I paired one with a relay shield and now I can control everything on my work bench by talking to my phone. My phone then talks to me in response. Cheap and easy automation.(Jarvis like) GS5. Joshua Stanton 1sheeld customer
