In this part 2 video I give a working demonstration of my raspberry pi controlled, TB6612FNG using lead screw door opener. I demonstrate it opening and closing with the stopping points controlled by limit switches.
If you are interested in the code running on the raspberry pi, each of the scrips I'm executing have been uploaded to github here: https://github.com/daretogo/duckdoor
