I would like to create a device to tell me how flat is the surface of a piece of wood.
Is there any way to use Arduino as a topography logger for that material, considering the highest difference won't be more than 1mm and almost of the time will be between 0,1mm and 0,9mm, and the width of the surface will be around 10cm.
The mechanical parts will be an another concerning. For this time I only want to know if someone use something as a sensor for this kind of usage.
