How can i know the angle of the vertical window blind by placing a small sensor on one of the blind slat
i am trying to make a arduino/esp8266 controlled window blinds, the controlling can be easily achieved in horizontal blinds, but my apartment has a vertical blind which are not interconnected at the bottom
Tried so far:
open and close based on time which it takes to open and close, but it keeps drifting over time
Cannot use light sensor to sense the ambient light, does not give correct information (day and night)
Tried to put a potentiometer on top of one of the blind slat ( no enough room to place things there, potentiometers have more friction)
any suggestions for angle sensor ?
