Micro-measuring by electrical palpation system , user interfaced by touchscreen / raspberry
This paper presents the interfacing of a work device positioning robot via a touchscreen display and a Raspberry computer . The application consists in handling a PWM signal from an interface that includes two linear graphic sliders, whose movement modifies the specific parameters of frequency and fill factor. Finally , the signal is amplified by controlling an electromagnetic actuator through which a work device ( a peak ) is moved in a controlled linear space .
