Well, no, but sort of.  This is a controller for the Gecko.  You can program
them to do what you want but this sounds like overkill for your project.  

You can take a Gecko and feed it a clock signal from a relatively simple
circuit.  

A really cheap solution is one of those little hobby kits.  You have a
variable pot that controls the
speed.   Unfortunately I can't remember any of the
kit names but a local electronic hobby supply shop should have one.  They
run in the $20-30 range IIRC.
