Reading Digital caliper with Arduino

[EdK]

Chuck,

I'm going to draw up a schematic to show how I think you have your digital caliper hooked up to the Arduino Uno board. Once we get that all figured out we can move on from there. In the mean time, can you take a picture of your caliper and post it? I think the code on Instructables might be for the older version of digital caliper, like the one I have, and the protocol has changed with the new ones.

How were you powering the digital caliper before you put the battery back in?
