Ok, wrong term, the capacitance in the transistor is working against me?
I am using the UNO (pin3 using analogWrite) connected to the 0-10V External Control Device on the Driver. I first looked into using DMX but it is way out of my league.
So getting rid of mosfets and the like, I have:
pin3 to Ext.in+
GND to Ext.in-
I'm at work, but will do a hand sketch and post it during lunch.
