Thanks for the reply!
Yes i did't say that quite right. Not 2 sketches but 2 "operations". It is counting up the display and also the LDR is reading, monitored on the serial monitor and #13 LED blinking. But they are not "interacting". I need to remove the mills and replace it with advance by 1 from the LDR, i guess.
I will try the suggestion from tuxdiuno. I should put that code inplace of the mill?
