Did you know the inexpensive Pittsburgh / Chicago Tool / Harbor Freight Calipers (4 pin dataport under battery cover) have a digital interface? We can read that interface with an Arduino, just like we do with the Mitutoyo / Igaging calipers and micrometers. The electrical interface is different, as is the data stream. Now, thanks to the hard work and experimentation of the folks at Arduinotronics, you can integrate measurement into your projects.
You can display the results on a LCD screen, save to a SDcard, or log the data to a Raspberry Pi based database.
I’ll be posting video, code and schematic shortly, but get your board order in now so you can get started! $20 + S&H
