Hi Doddy,

A couple of questions.
1. Can a logic input float or does it need to be strapped to ground with a 10k resistor?
2. Do the CW and CCW buttons operate independantly or do you have to press one of them for movement and the other at the same time to change direction.

When operating a module from an arduino, I make it standard practice to have a resistor to ground on the input (I have been caught out big time in the past with floating logic)
