Hi,

My goal is to measure a very fine wire with 10 µm (or better) precision using the arduino. I've been looking around for a way to do this and I could not find anything other than laser micrometer. (i.e. http://www.micro-epsilon.com/optical-micrometer/micrometer/optoCONTROL_1200/index.html)

Is anyone familiar with a strategy/way to achieve this in a DIY fashion using the arduino. What kind of sensors would you need?

Thank you

Boots
