In my previous post Introduction to Stepper Motors and How they Work, we had a look at stepper motors and how they work. This post will deal with the programming and circuitry involved in the stepper motor interface with PIC microcontroller. Usually a microcontroller is used to produce the stepping...

Stepper motor is a specially designed DC motor that can be driven by giving excitation pulses to the phase windings. They cannot be driven by just connecting the positive and negative leads of the power supply. They are driven by a stepping sequence which is generated by a controller. The...
