Getting windows to input keystrokes at a set time

[peter]

We have a microscope camera that I would like to do interval timing with, the software only allows single shots. Is there a what of telling windows to perform a set of keystrokes at a given interval?
Have been on Google for a while but have not found anything suitable.
Thanks

Couple that with Windows Task Scheduler
