Sending iGaging Caliper Data to Arduino to use as DRO

This is an overview of how to read the binary data from an iGaging digital caliper using the USB data port connection. I have verified that this also works on iGaging speedmic digital micrometer and digital dial indicator. This should also work on Mitutoyo products with a data port. This is largely based on this article from instructables - http://www.instructables.com/id/Inter...
