I finally got it working!  I'll be doing a writeup soon, but for now here is a demo video of 1 out of the 14 shutters I want to automate in the house.  The wire going to the motor will be run to the crawlspace below the house from inside the window sill, so it will never be seen. The humming noise will also be adjusted (I have the delay set too long in this demo) so it won't be as loud. There are 10 exact positions I can set them to, ranging from closed in one direction to closed in the other.
