I would like to test continuity from one end of a harness to another. Each end has 110 connections.
I would like to automate this test as it's quicker than using a DVM!
As I'm limited by the number of I/O pins available on an Arduino, does anyone have any thoughts on how this can be achieved?
Ideally I would like to pulse a pin and read the other end as an input. All the other inputs will be read to make sure no voltage is read back for each pin. This will inform me of any shorts and do a proper cross check on all pins.
Thanks in advance!
