I have followed with this article on instructables:http://www.instructables.com/id/Temperature-Detecting-Heating-Control-System-with-/. But I cannot get the same display info on the LCD. Is there something wrong with the code? Thanks!
Where does an electric imp come into that? I think you would do better on an Arduino forum.
Somehow, that Arduino method seems over-complicated. It would be so much easier with an imp as you would not need the display. Your browser (or one of the cool generic smartphone apps) is the user interface.
