5V trigger every other second

[OtoGuy]

How can I send a +5v trigger pulse for one second, then break for one second, then send another +5v trigger, etc?

My biggest problem is having the 1 second pause between pulses. The pause is to allow a peripheral nerve enough time to recover from stimulation. I apologize if this is a very basic question, I am quite new to this programming environment, or any programming environment for that matter.

Thanks for your help.

What kind of hardware do you use to send out the trigger?

And what timing requirements do you have? 

Attached is a simple software timed version. Lot's of room for improvements, see timed loop or timed sequence . If you have the IO hardware you can do very precise hardware timing.
