The Arduino connects to the Mitutoyo cable with a few components. A 2x5 shrouded header that mates to the female plug on the cable, a PN2222A transistor, and two 10k Ohm resistors. One resistor is used with the PN2222A to protect the micrometer (or caliper) from excessive voltage, the...
and here’ssome info about DIY interfacing that with Arduino. Unfortunately, the micrometer, being in their cheaper product range, doesn’t use this same standard. Instead, it’s got a regular old USB plug up top.
Bright-field images of a stage micrometer (OBM1/100SQ, Olympus) with lines at 10-μm intervals were captured at the center and four peripheral positions of the effective field of view (FOV). By dividing the distance of 200 μm by the number of pixels on the image, the pixel sizes we...
Plate separation was measured by a digital micrometer (IP65–Mitutoyo, Kawasaki, Japan). Lastly, the full chip assembly was filled with 5 cSt silicone oil (Sigma–Aldrich, St. Louis, MO, USA) immediately before use. For an overview of the chip assembly, see Figure S1a,b. 2.2. DMF ...
