Stepper motor control - part 3:

Having built the PCB and secured it to the front panel, you should be ready to take the stepper motor control into use. This is best done in step-by-step fashion (pun intended), and we will guide you from adjusting the step-down voltage regulator right up to operating the PC terminal program. In the unfortunate case of the project not working as expected, help is available in the section ‘Faultfinding’.
