I live in an apartment where I cannot change anything. I would like to have my blinds open/close via computer (any interface controllable via RPi/Arduino is fine). It's not required to also roll them up/down but would be nice.
The blinds are rolled up/down via a cord, as usual. They can be open/closed via a "stick" that's rotated. My blinds look like this:
I could image attaching a small rotating motor to the stick to open/close the blinds could do the job.
I found many solutions which require to change the blinds. Is there a project/solution which just attaches a small machine to the wall next to the window and has an arm to open/close the blends?
