Hi, if all you need is a single pulse, it's easy, just hook a cap about .1 mf or so in series with a test probe, touch your probe to a 5 volt source, and then to the input you need to pulse, you can vary the pulse duration by varying the size of the cap, if you have a scope, you can observe the result.
