I have a stepper motor and I don't know how to power it?
So I have a stepper motor made by Airpax with the label LB82773-M1 and it says it takes 5V 6.25 Ohms 7.5 Degree/Step. It has four leads two going to the posterior section of the motor and two going to the anterior section of the motor the leads are colored ad stated: Lead 1 & 2 (these leads go to the posterior section) are grey and red respectively; Lead 3 & 4 (these leads go to the anterior section) are black and yellow respectively. I'd like to use this perhaps for a bike generator. I just can't figure out how to make the stupid thing turn.
