The button to the stepper motor status signal, so that stepper motor based on a single pulse of the frequency of the signal and number of pulses to control a stepper motor acceleration and deceleration

Gives by the button step-by-steps the electrical machinery condition signal, causes to step-by-step the electrical machinery controls according to the monolithic integrated circuit pulse signal frequency and the pulse number step-by-steps the electrical machinery acceleration and the deceleration

By button signals the State of stepping motor, stepping motor based on single chip of pulse frequency and pulse to stepping motor controlled acceleration and deceleration
