//im trying to create a code for arduino that will open and close a door using a servo and photocell and display on lcd when the door open and closes, im not sure how to make it work i created functions but somehow its not calling the servo to function. the photocell is supposed to open door at 7am or when theres 30% light and close door when theres 40% darkness. it should call servo to function when it meets those requirements my code could be way off im not sure. any help is welcome step by step thanks.
