digitalWrite(openmotoropenplus, LOW); // sets the digital pin as output
is simply stating the obvious incorrectly.
How? Example showing correct would help.
Well, for a start, it doesn't make the pin an output, it was made an output with a "pinMode".
Your comment might have read "Set the pin low." or "write zero to the pin", but that doesn't describe what that actually achieves, which is what should be commented, if a comment is needed.
