I have a tutorial already done regarding servos , but it is heavily based off your tutorial. How should I credit you in the tutorial?
Ideally you don't want to duplicate content, just link over and say, 'for more info on blah blah blah, see this link'.
On certain occasions, you just want to give the reader a quick summary of some other work, in which case you'd do something like:
"Due to noise and control circuitry requirements, servos are less efficient than DC motors uncontrolled." - admin, [link
(notice how the link goes directly to the content, and not just the page)
If you want to be professional, such as for publishing a book, you can also use the IEEE accepted reference format (just look at my robot fish papers for examples).
FYI, I do plan to rewrite a lot of my older tutorials in the coming months . . . they are rather embarrassing to my standards/knowledge today . . . so give me a heads up on any quotes in case I make changes . . .
