NO!

If I recall correctly, the speed controllers are expecting a short pulse every 20msec or so. They accept a relatively wide range of base frequencies. The important thing is the pulse width. I believe that a 2msec pulse width is full stop. 2.5 msec pulse is full forward and 1.5 msec is full reverse.

I am going strictly from memory so don't quote me. The idea is right but the absolute numbers are probably wrong.

In any case, this is not too hard to make a "555" timer circuit that would turn a voltage of 0-5 into the right pulse train. I suppose that there are even custom IC's that would do it for you. Better yet, if you have an extra Stamp2 laying about you can fairly easily make it do the interface for you.

Good luck,
