I am going to control some vernetian blinds with an arduino. Ive managed to mount a small geared motor inside already, but i need to know the limits of the blind is. I was thinking of using a potentiometer so i can also see the position by the feedback of the voltage. I can mount this in the blind quiet easily too.
Now i am worried about over time the potentiometer will wear and spike, so i am just wondering if there is a better way?
The blind has a 4mm D shaped shaft all the way threw it, and the potentiometer also provides a solid limit too.
