It deals with the analysis of signals in metals, especially the ferromagnetic behavior when faced with variations, and the production of stress in the metal. What you can do to get quick analysis of metallic materials, by interaction of hardware and software can perform four-point test to measure resistivity, can evaluate cracks, listen to the barkhausen effect, see graphs via serial monitor , and finally the possibility of interacting with ultrasound through sensors, all of this is achieved through interaction with the lcd screen.
