I thank everybody who had suggestions. Some people thought they were smart
 asses and suggested a 555. Well, at first I had a 555 timer connected to a
 cd4020B. The amount of time out was adjustable by a 250K pot connected from pin
 7 to pin 2&6. The output was connected to a couple of txers that controlled a
 MOC3010. I just figured that I could implement a PIC to make the project more
 of a learning experience since I am new to these MCU's. Once again thank you to
 everybody that had some "positive" input.
