Sir, check this out…
I have a video of the AI-64 w/ the Servo Cape and it is going from degree 0, to degree 90, and then to the maximum. Which in my case w/ this servo is about 180 degrees. The flask app is running and the source, this html page that is rendered, allows for communication back to the servo via the Servo Cape and source running on the BBAI-64.
Also…changing some permissions proved valuable (I think). A lot of the files so far are only accessed via root. So, instead of running sudo python3 My_File.py, I just used chown to alter the groups and permissions.
Also, the chmod command does nothing so far, i.e. chmod +x My_File.py does not allow for my usage of ./My_File.py for whatever reason. I get that error code from above: The Video!

P.S. Enjoy and thank you.
