Basic Stepper Motor Control with a Parallax Propeller

This is a demonstration of basic unipolar stepper motor control with 2 pushbuttons dictating the direction. This video shows half-stepping action at about as fast as these particular motors will spin without locking up.
Logic (input reading/step sequenceing) is handled by a Parallax Propeller.
Power for the Steppers is a 5V supply with 4 2N3055 transistors.

They are 2N3055s

BADASS im trying to do the same thing you think you can help me with coding and stuff

I love it how they always use the term "SIMPLE". No matter who you meet, it's always easy, whether they are making an infrared sensor, stepper motor or a humanoid robot, or just bake a fucking apple pie... simple >_< If it was so fucking simple, why do we have universities???

[Andy205ro]

can use that for controlling a telescop ?

[MrCrazyeyes001]

what size is the motor, and where did you buy it from?

[purna2659]

That's it what you have?

So, I don't really have a good understanding of stepper motors yet. From what I understand the sequence in which the coils are "pulsed" determines the direction (1 and 2, 2 and 3, 3 and 1, so on)? So to change direction with a stepper you just reverse the sequence? No need for an H-Bridge?

@seriousninja Because parallel port gives digital ouputs that are easy to control with software.
