My new Seeeduino v3.0 arduino clone arrived today from Cool Components.
As a test I hooked up a DHT11 temp sensor and it all worked a treat. I like the colours too!
So now I know that the office got up to 22 deg C and 49% humidity.
I have added a Arduino page with some details of how I compiled the code without the GUI as at the moment running the GUI crashes my X server and logs me out.
