This project shows how to use an Arduino to read the signal from a set of digital calipers and send the reading over USB. In other words it adds USB functionality to digital calipers. A great reference on reading digital callipers can be found here . This project explores the details of another protocol found to be in use on some callipers. Check project details on the link below.
