Block control stepper motor
The block provides a convenient control interface for bipolar and unipolar stepper motors. To control a stepper motor depending on its type (bipolar or unipolar) and the chosen method of connection will need some additional electronic components.
Unipolar stepper motor control using 4 outputs. This is used to connect driver chip load ULN2003 or ULN2004
Bipolar stepper motor control 4 output. The connection using the IC SN754410NE
