Closed Loop Current Control

Although our Porters have current limiting which can be adjusted, they were not really designed to provide an active closed loop current control mode.

So many thanks to Ian Beaver for making public a neat way of adding closed loop current control using an Arduino and an external current sensor, full details can be found in Github here.

This method will also work on the DNO range and most of our earlier models, it is not required for the Pro-160 which has this functionality built in.
