It's usually good to at least look at the requirements to see what kind of problems can come up.
DIY projects get a load of leeway but this one is actively dangerous and missing really important safety features outside of the remote operation stuff in this thread. If OP is lucky it'll be the garage door instead of an arm or their car because there's no break beam or current monitoring so the motor will happily pin and crush someone unless it stalls out.
Does the project clearly state so?
I think such lack of warning is the point here. Note that a warning should include an indication of consequences.
The current disclaimer in the readme just points to electric shock. Not to the wealth of known hazards from malfunctioning electric garage openers, referenced further up in the thread.
