Make control with 2 pin output.

[gartner-dk]

Hi
Thanks for a great help with my project but I wish I had a diode that gave light so I could see what function I had activated I am a little new to it has so can not just see how to program myself out of so if you have activated eg 10 degrees then there is a diode that lights up in the button or next to it.
Hope someone can help me.

Have attached a picture the first model I have made without light.
and the code i use.

Yours sincerely
Mikael
