100% lost on stepper motor and driver

Forum 2005-2010 (read only) General Frequently-Asked Questions
#1

Motor is a Mitsumi Step Motor m68sp-1

And driver is a UCN5804B http://www.alldatasheet.com/datasheet-pdf/pdf/55138/ALLEGRO/UCN5804B.html

Friend gave me these part's to experiment with and following a weird guide that says motor is from a commodore 64

Call yellow A, black B, orange C, and brown D. To rotate the motor in one direction, ground (in turn), A, B, C, D (one at a time). For the other direction, the sequence is A, D, C, B.

I can get it to spin forward but not backwards (it tries but it takes a step forward then a step back kinda thing)

and i cant figure out how to hook it up to the control driver

#2

What hardware are you using to interface the motor with your arduino? Are you using any of the stepper motor libraries available?

#3

i may be in the wrong area of forum i was just wondering where the pins connect to on the driver

I don't own an arduino yet but will soon

#4

Do you have the ground from your Vcc Supply connected to the ground of the +5V you use for step input & direction? (You should)

Good luck!
