Power to electric motors from a digital controller is never easy

Hooking up 2 electric drive motors seems like a simple task on the surface, but never is in practice.  Here’s my mockup of a circuit I’m going to use.  The meat of the control circuit is an L293D Quadruple Half-H Driver. Now that the breadboard prototype is working, it’s time to assemble the thing permanently on a printed circuit board.  Leave a comment if you want the schematic for this, it works pretty well with no noticeable gitter thanks to a bunch of capacitors.
