Thanks Dave,

I read that one yesterday and, while I'm not opposed to building with discrete components, the cost is somewhat higher. Also, more components to mount and solder into the pcb.

The L298HN is an IC that seems to be popular and I have found some circuitry and code to control direction but just need to add the PWM speed control.

Anyway, the code in Scott Edwards article seemed pretty simple so I wasn't sure if it offered a good smooth speed control. Guess I could breadboard it and see...

Regards,
Mitch
