Microcontroller for Pulse Coil? 1

[Cburg]

Dear Group,
I need to control a pulse coil firing with a selectable time base program. I need to be able to select a number of operating frequencies, and these need to change slowly over a range of values. All frequencies will be below 15 Hz. The output will drive a small signal relay (through a darlington). Output duty cycle needs to be programmable.
What is the easiest and cheapest way to accomplish this? I am looking at microcontrollers. How big a project is it to program one of these? Is there a commercial unit that easily accomplishes this?
Thank you for your help!
Sincerely,
Mike

One of the Paralax Basic Stamps, or an Arduino if you wany it quick and dirty. Or a PIC. Anything goes. Basic Stamps are very basic and you will do the programming the first day.
