Here's a [good reference](https://sites.google.com/site/marthalprojects/home/arduino/arduino-reads-digital-caliper) for getting initial results. I made a few changes in code including printing binary packets for debugging, and flipping all of the reads (we are using a level shifter not a transistor). See below for a simple breadboarded circuit to get up and running.
Raw scope readings (reading a 0.01mm) can be seen below, transmitted over seven 4-bit chunks. The readings are fixed point with the two LSB in decimal being devoted to 100 and 10 um significant figures. The 21st bit is devoted to measurement sign, and one of the remaining bits is used for unit conversion, while some are unused.
