Tedd OKANO / Mbed 2 deprecated unipolar_stepper_motor_operation_sample

Very simple operation samples of unipolar stepper motor. This code has been made to help beginners to learn the stepper motor. The history of the code shows the how to generate pulses from very basic level.

Dependencies:   mbed
