Hi,
I'm thinking of building a simple tester to test a board that has 2 connectors (no other components, it's a simple connection board). Need to test as solder joints can't be visually seen.
My thought was to connect all pins of both connectors to IO pins, then set them high 1 at the time and check that only the correct pins are high. Would this work if I connect them directly to Arduino digital ports? Are there any precautions that should be added so that shorted board doesn't damage the Arduino?
Thanks
