Mechanical parts for automated curtain control Answered
I am building an automated curtain control, based on an ESP8266, to be controlled by the sun comming up (or going down) or by time or by smartphone. The electronics and software are all but complete, but I do have a problem...
First, how can I open and close the curtains? I was thinking about a fishing wire in a loop, but how do I get enough traction from a pulley to move the curtains?
Second, how can I make sure that the curtains can be opened and closed manualy, without frying the motor?
Third, how do I detect the position of the curtain?
